what is the difference between the terms endocytosis and exocytosis?

Endocytosis is the process of capturing a substance or particle from outside the cell by engulfing it with the cell membrane, and bringing it into the cell. Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell.

The difference between transpiration and translocation are as follows : 1) Transpiration is the process of loss of excess water from the plants while Translocation is the transport of of prepared food from to different parts of the plant.

Pinocytosis is a type of endocytosis involved in the transport of particles sized 0.5 µm or less. Phagocytosis involves the formation of pseudopodia (false feet) for the intake of molecules. Pinocytosis intakes the particles via invagination and formation of pockets in the cell membrane.

What is the difference between osmosis and diffusion? Osmosis is the movement of water molecules through the cell. Diffusion is the movement of molecules, such as oxygen, in and out of a cell. ... The movement of materials through the cell membrane need to use the cell's supply of own energy.

These proteins are characterized by being open to both the intracellular and extracellular space at the same time. By contrast, carrier proteins are only open to the inside or outside of a cell at any given time. Channels or pores are typically designed so that only one specific substance can pass through.

Receptor-mediated endocytosis allows cells to take up large amounts of molecules that are relatively rare (present in low concentrations) in the extracellular fluid 2,3start superscript, 2, comma, 3, end superscript.

Phagocytosis (literally, “cell eating”) is a form of endocytosis in which large particles, such as cells or cellular debris, are transported into the cell. We've already seen one example of phagocytosis, because this is the type of endocytosis used by the macrophage in the article opener to engulf a pathogen.

Animals. In animal cells, vacuoles perform mostly subordinate roles, assisting in larger processes of exocytosis and endocytosis. Animal vacuoles are smaller than their plant counterparts but also usually greater in number. There are also animal cells that do not have any vacuoles.

Endocytosis is a type of active transport that moves particles, such as large molecules, parts of cells, and even whole cells, into a cell.

Endocytosis takes particles into the cell that are too large to passively cross the cell membrane. Phagocytosis is the taking in of large food particles, while pinocytosis takes in liquid particles. Receptor-mediated endocytosis uses special receptor proteins to help carry large particles across the cell membrane.

But the difference between excretion and secretion is that excretion is the removal of waste from the body that has no further use while secretion is the movement of materials from one part of the body to another.

Receptor-mediated endocytosis is a form of endocytosis in which receptor proteins on the cell surface are used to capture a specific target molecule. The receptors, which are transmembrane proteins, cluster in regions of the plasma membrane known as coated pits.

So the sole difference between fusion and endocytosis is that in endocytosis, the virus just straight-up penetrates through the host while in fusion it's more meticulous about the envelope and capsid? ... Only enveloped viruses can enter a cell by fusion. Endocytosis uses a vesicle to bring the virus into the cell.

The major difference is that Exocrine glands secrete substances out of the body and Endocrine glands secrete substances into capillaries and blood vessels.

Although receptor-mediated endocytosis is intended to bring useful substances into the cell, other, less friendly particles may gain entry by the same route. Flu viruses, diphtheria, and cholera toxin all use receptor-mediated endocytosis pathways to gain entry into cells.

Other than the fact that vacuoles are somewhat larger than vesicles, there is a very subtle distinction between them: the membranes of vesicles can fuse with either the plasma membrane or other membrane systems within the cell. The membrane of a vacuole does not fuse with the membranes of other cellular components.

Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell. Both endocytosis and exocytosis are active transport processes.
