Energy is a number. A quantity. And the quantity itself isn’t even particularly fundamental. Instead, it’s a mathematical relationship between other, more fundamental quantities. It was 17th century polymath Gottfried Leibnitz who first figured out the mathematical form of what we call kinetic energy – the energy of motion. He realized that the sum of mass times velocity squared for a system of particles bouncing around on a flat surface is always conserved, assuming no friction and perfect bounciness. Leibnitz called this early incarnation of energy vis viva – the living force.

Why Does Time Go Forward?

Why does time go forward? How does Entropy relate to the direction of time? What really is time, and what gives it a direction? The Arrow of Time. Hi! I'm Jade. I draw pictures that move and become animated physics videos. ***SUBSCRIBE*** https://www.youtube.com/c/upandatom ***Let's be friends*** TWITTER: https://twitter.com/upndatom?lang=en ***MORE VIDEOS YOU'LL LOVE*** 50 AMAZING Physics Facts to Blow Your Mind! https://youtu.be/BUebQNPBLSo Could Quantum Superposition Stop a Bomb Exploding?https://youtu.be/wiW7jhdKDVA MUSIC: http://www.bensound.com Thanks for watching! __________________________________________________________________ We all think of time as having a direction. Yesterday is the past, tomorrow is the future. But what if I told you that none of the equations that govern our universe have anything to do with the direction of time. So what gives time its direction? The arrow of time is given purely by the second law of thermodynamics. The second law of thermodynamics says that the ENTROPY of the universe is always increasing. Entropy is the measure of randomness and disorder of a system. One day our universe will reach a point of maximum entropy, and time as we know it will cease to exist. There will be no distinction between past, present and future. This one aspect of our universe (entropy) is what gives time its arrow. In the past there was lower entropy than now, and in the future there will be higher entropy. So why is Entropy always increasing? Well, disorder is more likely than order. There are plenty of ways to be in a disordered state, while there are very few ways to be in an ordered state. Disorder is more probable than order. The real question is, why was entropy ever low in the first place? It seems kind of strange that such an unlikely event should happen. This question is one of the biggest unsolved mysteries in physics. One theory is that we live in a multiverse, where baby universes are being born all the time. The baby universe start with low entropy, but the entropy of the entire multiverse increases. If physicists manage to crack that one, all questions will be answered, we'd be able to understand the mysteries of our universe and the Arrow of Time.

Our Solar System is Moving into a Potentially Dangerous Interstellar Energy Cloud
 
15:56
Our solar system is moving into a potentially dangerous and destabilizing interstellar energy cloud. The solar system is travelling through much stormier skies than we thought, and might even be about to pop out of the huge gas cloud we have been gliding through for at least 45,000 years. That’s the implication of a multi-decade survey of the interstellar wind buffeting the solar system, which has revealed an unexpected change in the wind’s direction. The edge of the solar system is roughly defined by the heliosphere, a giant magnetic bubble blown by charged particles streaming from the sun. This bubble shields Earth from much of the interstellar wind, so a change in the wind’s direction will have little effect here on the ground. But the change does tell us something surprising about our galactic surroundings. The cloud is so large and diffuse, it was previously assumed to be relatively calm, and that the wind would blow in the same direction for millions of years. The fact that the wind is shifting over the span of mere decades means that the interior of the cloud is either unusually turbulent, or that the solar system is a mere 1000 or so years away from punching its way out. “While there had been hints that something was changing in the environment of the sun, when we finally put all the historical data together it became clear that one can make a strong scientific statement that this change has actually occurred,” says Frisch. What the change means is still up for debate. We could be nearing the cloud’s edge, or we could still be in the thick of it, pushing our way through an interstellar storm.

How Radio Waves Are Produced
 
04:58
UNLOCKING THE MYSTERIES BEHIND RADIO WAVES. Electric current creates magnetic field, oscillating electric current creates oscillating magnetic field and not "electromagnetic wave" as current belief. Electron has a standing- electric field and magnetic field at right angle (watch video structure of electron). The flow of electrons in a conductor is essentially caused by the attraction between the electric fields of mobile electrons and "fixed" positive charges in the conductor. Oscillation of electrons in a conductor is caused by the alternation of electric polarity in the conductor. Because of electric field and magnetic field of an electron is at right angle, when oscillates the electric field of the electron will be parallel to the oscillation and magnetic field will be perpendicular to the oscillation.This oscillation of the electron creates transverse wave on its magnetic line and the oscillating magnetic line is radiated to space. http://www.amazon.com/author/atom http://www.facebook.com/novaphysica https://www.youtube.com/user/atommodel

And when you're somewhere cold, then sound will travel slow, and up in space it travels nowhere. 'Cause sound changes the pressure of a medium, whether oxygen, hydrogen even calcium. It needs molecules around it to vibrate, to travel to any place. Ohhh, temperature, sea level, and molecular composition of solids, gas and liquids, these are things that affect the speed of sound.

The word usually refers to visible light, which is visible to the human eye and is responsible for the sense of sight.[1] Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), or 4.00 × 10−7 to 7.00 × 10−7 m, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths).[2][3] This wavelength means a frequency range of roughly 430–750 terahertz (THz). The main source of light on Earth is the Sun. Sunlight provides the energy that green plants use to create sugars mostly in the form of starches, which release energy into the living things that digest them. This process of photosynthesis provides virtually all the energy used by living things. Historically, another important source of light for humans has been fire, from ancient campfires to modern kerosene lamps. With the development of electric lights and power systems, electric lighting has effectively replaced firelight. Some species of animals generate their own light, a process called bioluminescence. For example, fireflies use light to locate mates, and vampire squids use it to hide themselves from prey. The primary properties of visible light are intensity, propagation direction, frequency or wavelength spectrum, and polarization, while its speed in a vacuum, 299,792,458 metres per second, is one of the fundamental constants of nature. Visible light, as with all types of electromagnetic radiation (EMR), is experimentally found to always move at this speed in a vacuum.[citation needed] In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not.[4][5] In this sense, gamma rays, X-rays, microwaves and radio waves are also light. Like all types of light, visible light is emitted and absorbed in tiny "packets" called photons and exhibits properties of both waves and particles. This property is referred to as the wave–particle duality. The study of light, known as optics, is an important research area in modern physics." Wikipedia contributors. "Light."

3 Things 'Faster Than Light'
 
03:50
These 3 things go "faster" than the speed of light. How's that even possible? Subscribe: http://www.youtube.com/channel/UCj1gf... ↓Want more info?↓ More about the experiment: Marissa Giustina’s research: http://arxiv.org/abs/1511.03190 Advanced scientific note about Doppler: If there is a light moving away from you at constant velocity in static flat (Minkowski) space-time, no matter how red it is, you will never conclude it is going faster than light. But, here I am discussing the conclusions one might come to if you mistakenly use Doppler in the context of the curved space-time of the universe (where there is expansion). Interpreting the huge redshift as a result of the doppler effect, could make one think that galaxies we see are moving away at speeds approaching light speed. And since what we are actually seeing is light from those galaxies from billions of years ago, and given that the universe is expanding, you might be tempted to say that they have since "accelerated" to faster than the speed of light. You might go further and say that there are more distant galaxies that we can't see which are moving away even faster. So you might conclude there are galaxies moving faster than light in the universe. But the redshift isn't from doppler and this "acceleration" of the expanding universe isn't actually causing a true increase in velocity. Sometimes astronomers do say there is a faster than light "recession speed" by pretending the expansion of the universe is causing distant galaxies to move away from each other at a corresponding velocity, but that's misleading. In general relativity, you can actually have an increase in space between objects without causing a corresponding increase in the relatives velocities of those objects.

Space-Time And The Speed Of Light | Einstein's Relativity
 
05:43
http://facebook.com/ScienceReason ... Albert Einstein's Theory of Relativity (Chapter 3): Space-Time And The Speed Of Light The concept of spacetime combines space and time to a single abstract "space", for which a unified coordinate system is chosen. Typically three spatial dimensions (length, width, height), and one temporal dimension (time) are required. Dimensions are independent components of a coordinate grid needed to locate a point in a certain defined "space" --- Please subscribe to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceMagazine • http://www.youtube.com/ScienceTV • http://www.youtube.com/FFreeThinker --- SPACETIME In physics, spacetime (or space-time) is any mathematical model that combines space and time into a single continuum. Spacetime is usually interpreted with space being three-dimensional and time playing the role of a fourth dimension that is of a different sort from the spatial dimensions. According to certain Euclidean space perceptions, the universe has three dimensions of space and one dimension of time. By combining space and time into a single manifold, physicists have significantly simplified a large number of physical theories, as well as described in a more uniform way the workings of the universe at both the supergalactic and subatomic levels. In classical mechanics, the use of Euclidean space instead of spacetime is appropriate, as time is treated as universal and constant, being independent of the state of motion of an observer. In relativistic contexts, however, time cannot be separated from the three dimensions of space, because the observed rate at which time passes for an object depends on the object's velocity relative to the observer and also on the strength of intense gravitational fields, which can slow the passage of time. • http://en.wikipedia.org/wiki/Spacetime --- GENERAL RELATIVITY Special relativity is a theory of the structure of spacetime. It was introduced in Albert Einstein's 1905 paper "On the Electrodynamics of Moving Bodies" (for the contributions of many other physicists see History of special relativity). Special relativity is based on two postulates which are contradictory in classical mechanics: 1. The laws of physics are the same for all observers in uniform motion relative to one another (principle of relativity), 2. The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the source of the light. The resultant theory agrees with experiment better than classical mechanics, e.g. in the Michelson-Morley experiment that supports postulate 2, but also has many surprising consequences. Some of these are: * Relativity of simultaneity: Two events, simultaneous for one observer, may not be simultaneous for another observer if the observers are in relative motion. * Time dilation: Moving clocks are measured to tick more slowly than an observer's "stationary" clock. * Length contraction: Objects are measured to be shortened in the direction that they are moving with respect to the observer. * Mass-energy equivalence: E = mc2, energy and mass are equivalent and transmutable. * Maximum speed is finite: No physical object or message or field line can travel faster than light. The defining feature of special relativity is the replacement of the Galilean transformations of classical mechanics by the Lorentz transformations. (See Maxwell's equations of electromagnetism and introduction to special relativity). • http://en.wikipedia.org/wiki/Theory_of_relativity .

Water rotating in a magnetic field
 
02:09
Youtube is changing the policies. Please subscribe to my channel so that I can continue to make movies like this! When an electrical charge travels through a magnetic field, in a direction perpendicular to the field, it is deflected in a 3rd dimension in a direction perpendicular to both the direction of its own movement and the direction of the field. The result in this experiment is that the water rotates. The same principle is used in the cathode ray tube used in old television sets. There the charges move through vacuum, whereas here they move through water. Update 2018-08-09: The rule that determines which of the two perpendicular directions will be the case is usually called "Fleming's Left Hand Rule". See an explanation of this rule here https://www.electrical4u.com/fleming-left-hand-rule-and-fleming-right-hand-rule/ . Exactly why the rule is that way, and not the other way around, requires a longer explanation, and they touch upon it on that page. If the magnet is flipped, or if the current direction is flipped, then the rotational direction will also flip. If both magnet and current is flipped, the rotational direction will not change. I should also clarify what I indicated in my original description that it is the ions in the water (sodium ions and chloride ions) that are deflected (causing rotation) and they in turn cause the water to rotate with them, so it is not the water directly that rotates so to say. I got a question related to this: Is it because of the polarising effect of water molecules? Here is what I replied: Not exactly, it is because ions from the salt in the water (i.e. charges) are moving between the center pin and the circumference. Charges moving in a magnetic field are deflected. The water is pulled along with them. There are both negative and positive ions, so they move both towards the pin and away from the pin. The net effect of those two radial movements is zero so to say, so water is not moving in any of these two radial directions. But both the negative and the positive ions move in the same deflected direction (which is one of the two directions that are perpendicular to the radial directions) so there is a net effect of that movement, and that pulls the water along. So rotation occurs. Here is another related question: Which charge is rotating ? Na +ive or Cl -ive ? My reply: Both are rotating and both have the same rotational direction. The rotation of a moving charge is determined by the direction of the magnetic field and the direction of the electrical current that the moving charge corresponds to. The Na+ ions and the Cl- ions are of course moving in opposite directions, but they both correspond to an electrical current going in one and the same direction. In other words, when Na+ ions are going in one direction, they represent a current going in the same direction as the current corresponding to Cl- ions going in the opposite direction compared to the direction of the Na+ ions. You can understand this easily if you think of a simple electrolyis situation. There you have positive ions going in one direction, and you have negative ions going in the opposite direction. But if you think of the electrical current, you have only one electrical current, and it is of course going in only one direction. So positive ions going to the left correspond to the same direction of electrical current as negative ions going to the right.

Native American Flute Music: Meditation Music for Shamanic Astral Projection, Healing Music
 
09:09:09
Native American Flute Music: Meditation Music for Shamanic Astral Projection, Healing Music Shamanism is a system for psychic, emotional, and spiritual healing and for exploration, discovery, and knowledge gathering about non-material worlds and states of mind. Shamanism is a "technique of ecstasy" in which the spirit of the shaman leaves the body and travels to communicate with spirit helpers and other beings for the purpose of obtaining knowledge, power, or healing. Shamanic Astral Projection or Shamanic Journeying is an altered state of consciousness wherein you enter a realm called non-ordinary reality. By journeying you can gather knowledge and perform healing in ways that are not accessible in ordinary waking reality. How does shamanism work? Some people think that in shamanic healing journeying, the spirit leaves the body and a person is being healed by spirit helpers. Others think that shamanic journeying allows access to one's own intuition, which may otherwise be drowned out by the prattle of everyday thinking or by anxiety; and that it is a way of engaging a person's subconscious desires for healing. Shamanic healing may not cure physical or psychological illness, but it may help one gain psychic energy that will allow one better to handle illness. Shamanic healing therefore is best used in conjunction with other treatments, not as a substitute for them. Connection with a Power Animal A power animal protects you physically and provides you with emotional support, wisdom, and vital energy. Some people think a power animal is a spirit being that stays with you because it cares for you and enjoys being able to experience life in a physical body. Others think a power animal is a symbol for one's subconscious wisdom. Almost everybody has a power animal; some have several. (Perhaps you had an "invisible animal friend" as a child or have always been fascinated with a particular kind of animal. This animal may be your Power Animal). A person may, in the course of life, lose contact with the power animal, thereby losing the animal's protection, wisdom, and energy. If you lose contact with your Power Animal, you may feel dispirited, or you may become sick easily. The Shamanic Astral Projection technique of Power Animal Retrieval can restore a person's connection to a Power Animal. A person can also journey to find his or her own Power Animal. To maintain a connection with your Power Animal, take the time to learn about your animal, learn to feel its presence, communicate with it, and honor it by doing things that it enjoys. Free flow of emotional and physical energy Health requires a free flow of energy that one can use to accomplish one's desires in the world. But one's energy can become blocked in various ways. People who have lost parts of their life essence, who have been ill, who have lost connection with a Power Animal, or who are regularly exposed to emotionally stressful situations are vulnerable to intrusions or "psychic infections" that block a person's connection with self or drain a person's energy. An intrusion can be thought of either as a foreign energy being that takes up residence in a person's psychic body (a psychic infection), or as a psychic structure (an emotional wall or barrier) that a person built to keep herself safe from harm, but that now is blocking some of his/her energy expression. A person with an intrusion might feel drained or ill, might have aches and pains, might have nightmares or other fears. A shamanic healer can find and remove intrusions and barriers in a healing ritual called extraction. A sense of purpose A sense of purpose is necessary to happiness. The person who loves and cares about the world and fellow beings, who wants to make some small part of the universe a better place, has a sense of purpose. A person can find a sense of purpose in life by seeking knowledge and direction through shamanic journeys, divinations, and rituals. One can do this alone, or with a group of people engaged in similar quests. A shamanic healer or counselor can't find another person's purpose, but can help one seek and interpret information. === SUBSCRIBE!

What causes wind to blow?
 
02:00
In this video we explain the science behind wind. What exactly is it and what causes it to blow? You can find more information on what causes wind to blow on the Met Office website: http://www.metoffice.gov.uk/learning/wind/what-causes-wind Wind is air in motion, travelling between areas of different pressure. To understand what causes this motion; we first need to understand a bit about air pressure. When air heats up, the atoms and molecules within it move faster and spread out. It is this reaction to heat that causes warm air to expand and rise, In colder air the molecules move more slowly and are closer together, which makes the air sink. When heat from the sun reflects off the Earth surface, it warms the air above it - this air will rise, leaving areas of lower pressure. In contrast, areas of higher pressure occur where the cooler air is located. When there is a difference in air pressure between two areas, air moves from the high pressure area to low pressure area to equalise the pressure. The best example of how this causes wind is in coastal areas. To learn more about the history of meteorology and the science behind the weather headlines, you can listen to our audio podcasts here: https://soundcloud.com/metofficepodcasts On sunny days, land warms up quicker than the sea, which reflects more of the sun’s rays. This creates a temperature contrast and, as the land heats up, it warms and expands the air above it. As this warm air expands, an area of low pressure is created over the land leaving relatively higher pressure over the sea. This pressure difference causes air to move from the sea to the land to equalise the pressure difference. That rush of air is the wind we experience. In this case, a sea breeze.

This is a really fun project and when you first see the results, chances are your jaw will drop. The main thing to keep in mind for this project is that you need a camera that shoots 24 fps. The effect that you are seeing can't be seen with the naked eye. The effect only works through the camera. However, there is a version of the project you can do where the effect would be visible with the naked eye. For that project, you'd have to use a strobe light. For this project you'll need: A powered speaker Water source Soft rubber hose Tone generating software 24 fps camera Tape. Run the rubber hose down past the speaker so that the hose touches the speaker. Leave about 1 or 2 inches of the hose hanging past the bottom of the speaker. Secure the hose to the speaker with tape or whatever works best for you. The goal is to make sure the hose is touching the actual speaker so that when the speaker produces sound (vibrates) it will vibrate the hose. Set up your camera and switch it to 24 fps. The higher the shutter speed the better the results. But also keep in the mind that the higher your shutter speed, the more light you need. Run an audio cable from your computer to the speaker. Set your tone generating software to 24hz and hit play.Turn on the water. Now look through the camera and watch the magic begin. If you want the water to look like it's moving backward set the frequency to 23hz. If you want to look like it's moving forward in slow motion set it to 25hz. Have fun!

How does electron move around nucleus? Gryzinski's free-fall atomic models for chemical elements
 
06:25
Discover the naked truth of quantum mechanics hidden behind the screen of psi function and see how electrons move in an atom! The free-fall atomic model was introduced in 1965 by Michael Gryzinski (1930-2004), a Polish nuclear and plasma physicist, as a result of adding electron's magnetic moment to Bohr's atomic picture. Gryzinski proposed the model as a consequence of his classical scattering theory. In this classical approximation, electrons don't circulate as in the Bohr model, but enter in almost radial free-fall towards the nucleus. Due to their magnetic moment, the Lorentz force bends the electron trajectories to return them to their initial radius. For more see https://en.wikipedia.org/wiki/Free-fall_atomic_model

Action Potential Explained - The Neuron
 
03:44
Action Potential Explained - The Neuron. An Action potential is the neurons way of transporting electrical signals from one cell to the next. This is a picture of a neuron, where you have dendrites in one end, and the axon terminal in the other end. In the middle of the neuron you will find the axon, which is where the electrical signal will travel from the dendrites to the axon terminal to the synapse. This is a picture of a myelinated neuron, which is covered with a myelin sheath that allows the electrical signal to travel faster through the axon. So instead of activating every ion channel down the axon, only channels in the small spaces between each myelin sheath called the Node of Ranvier is activated and generates an action potential. So lets take a closer look at the axon. On the membrane of the neuron, you will find small ion channels that are closed when the cell is in its resting state. The neuron is able to create an action potential because of the concentration difference of ions between the intracellular space and the extracellular space. There is a higher concentration of sodium ions outside the neuron and a higher concentration of potassium inside the neuron. the extracellular space is more positive than inside the neuron. This creates a voltage difference of -- 70 mV, which is created with the help of leaky ion channels that are more permeable to potassium ions than sodium ions, which will cause potassium to leave the cell and only small amount of sodium to enter. The sodium potassium pump also regulates the intracellular environment, by pumping out 3 sodium ions in exchange for 2 potassium ions. The -- 70 mV is the neurons resting potential, but when the neuron is stimulated by a presynaptic neuron, it causes sodium channels to open, letting in positive ions. This will change the electrical environment and make it more positive on the inside and less positive on the outside. This is called Depolarization, and which causes a chain reaction where the next sodium channels will open letting in positive ions, all the way down the axon. Shortly after a channels have opened, they will close again and potassium channels will then open letting out positive potassium ions, to recreate the negative environment inside the neuron and the positive environment outside. This happens at around + 40 mV, and causes a Repolarization where the intracellular space is becoming negative again. The neuron then reaches a state of Hyperpolarization where the cell has let out too many ions and has now become more negative than the cells resting potential. This is quickly corrected by the leaky channels and the sodium potassium pump, and the neuron stabilize at the resting potential at a -- 70 mV. The action potential that has traveled through the axon, reaches the axon terminal, where vesicles with neurotransmitters are released out into the synaptic cleft to transport the signal to another neuron.

Cell Membrane Transport - Transport Across A Membrane - How Do Things Move Across A Cell Membrane
 
10:50
In this video we discuss the different ways how substances transport across a cell membrane, including facilitated diffusion, channel mediated diffusion, carrier mediated diffusion, simple diffusion, passive transport and active transport. Transcript/Notes (partial) Substances move into and out of a cell through several different processes called membrane transport. There are two main processes, passive transport processes and active transport processes. The main difference between the two is that passive processes do not require energy expenditure and active processes do require cells to expend energy. Lets start by looking at the passive processes, which include simple diffusion, facilitated diffusion and osmosis. Diffusion is the movement of a substance from where it has a high concentration to where it has a low concentration, or the tendency of a substance to spread out evenly over a given space. Simple diffusion occurs with solutes that are small and non polar. By being non polar they can move in between the phosphoipid molecules that form the plasma membrane because the interior region of the membrane is non polar. Some of the materials that move by simple diffusion include the gases O2, CO2, and small fatty acids. So, if there is a higher concentration of oxygen O2 molecules outside of a cell, they can move down the concentration gradient, across the membrane without assistance, and into the cell as long as the concentration gradient exists. The second type of diffusion is facilitated diffusion. This applies to solutes that are small and either charged or polar. Because these solutes are polar, the non polar phospholipid bilayer blocks them from passing through the membrane and into or out of the cell by simple diffusion. However, they can pass into and out of the cell with the assistance of plasma membrane proteins through a process called facilitated diffusion. There are two types of facilitated diffusion, channel mediated diffusion and carrier mediated diffusion. The difference between the two is the type of transport protein used to move the substance across the membrane. Channel mediated diffusion is when a ion, which is a charged particle where its total number of electrons does not equal its total number of protons giving it a positive or negative charge, moves across the membrane through a water filled protein channel. Each protein channel is typically specific for one type of ion, and there are two types of channels, a leak channel, which is continuously open, and a gated channel, which only opens due to a stimulus, and only stays open for a fraction of a second. Carrier mediated diffusion involves the movement of polar molecules such as simple sugars or simple carbohydrates and amino acids across the membrane. This is accomplished by a carrier protein, which actually changes shape in the process. For instance glucose binds to a carrier protein, which changes shape and moves the glucose molecule to the other side of the membrane. Now for osmosis. Osmosis is the passive movement of water through a selectively permeable membrane. This occurs when there is a difference in concentration of water on either side of the membrane. This can happen in one of two ways, water can slip between the phospholipid molecules that make up the plasma membrane, or through integral protein water channels that are called aquaporins. Now lets look at active processes. As stated earlier, active processes require the use of cellular energy for membrane transport. There are two types of active processes, active transport and vesicular transport. Active transport is the movement of a solute against its concentration gradient, or going from an area of low concentration to a place of higher concentration. Vesicular transport is the transport of large substances across the plasma membrane by a vesicle, which is a membrane bound sac filled with materials. Active transport has two types, primary active transport and secondary active transport. In primary active transport cellular protein pumps called ion pumps move ions across the membrane, against their concentration gradient. In secondary active transport a substance is moved against its concentration gradient by using energy provided by a the movement of a second substance down its concentration gradient. There are two types of secondary active transports, symport, where two substances are moved in the same direction and antiport, where two substances are moved in opposite directions. Vesicular transport involves the transport of larger substances, such as proteins or large carbohydrate polysaccharides, across the plasma membrane. In exocytosis, materials are secreted from the cell to the interstitiual fluid outside the cell. In endocytosis the plasma membrane kind of traps a substance by folding inward. In phagocytosis a large particle is engulfed by the newly formed vesicle and this vesicle fuses with a lysosome.
