Let's talk a little bit about exocytosis which is how the cell is able to release larger molecules that might be used by the rest of the body other cells or maybe it's going to be part of the extracellular matrix and to understand how this works is really the reverse of endocytosis we're going to go and produce some proteins in the endoplasmic reticulum this is our classic example thoseIt is when cellular waste products travel in vesicles to the surface of the cell membrane and are released, thereby exiting the cell Cellular waste, such as broken down molecules that the cell cannot reuse, is discharged from the cell by the process of exocytosis Exocytosis is the opposite of endocytosis;

Exocytosis definition biology simple-0 Main Difference – Endocytosis vs Exocytosis Endocytosis and exocytosis are two mechanisms involved in the transport of matter through the lipid bilayer Both endocytosis and exocytosisThis is the process whereby the cell membrane of a cell extends toward a particle, engulfing it and encloses it within this folded membrane forming a phagosome The ingested material in the phagosome is later processed by cellular enzymes

Exocytosis Wikipedia

Exocytosis is the cellular process in which intracellular vesicles in the cytoplasm fuse with the plasma membrane and release or "secrete" their contents into the extracellular space Exocytosis can be constitutive (occurring all the time) or regulated Constitutive exocytosis is important in transporting proteins like receptors that function in the plasma membraneActive transport mechanisms require the use of the cell's energy, usually in the form of adenosine triphosphate (ATP) If a substance must move into the cell against its concentration gradient, that is, if the concentration of the substance inside the cell must be greater than its concentration in the extracellular fluid, the cell must use energy to move the substanceEndo/exocytosis This is the movement of very large molecules (or particles, bacteria or other organisms) across the cell membrane It involves the fusion of vesicles (containing the target/victim) with the cell membrane eg bacteria entering macrophages Substances destined for secretion are packaged in the Golgi body first

Endocytosis is a type of active transport that moves particles, such as large molecules, parts of cells, and even whole cells, into a cell There are different variations of endocytosis, but all share a common characteristic the plasma membrane of the cell invaginates, forming a pocket around the target particle In this article we discuss about the major difference between phagocytosis and pinocytosis is that a phagocytosis is a form of endocytosis that uptakes solids through the plasma membrane to the cell while pinocytosis is another form of endocytosis which uptakes fluids including solutes and small molecules through the plasma membrane to the cell 1) It gives shape and protection to cell 2) Transport material into and out of the cell 3) Act as a receptor site and recognize chemicals, hormones and neurotransmitter, and help in signaling 4) It is the boundary which separates the part of the cell from outer environment 5) It helps in exocytosis and endocytosis
