Endocytosis refers to O a. regeneration of brain cells O b. processes that occur at the neuromuscular junction collectively, the two types of refractory period d. processes of vesicle recovery after neurotransmitter release e. none of the above
During the process of active transport, large packages of tiny molecules are transported through the cell membrane by approach of vesicles – consider vesicles as very little membrane sacs that can fuse with the cell membrane.
The membrane of a cell are consists of a lipid bilayer. The walls of vesicles are made up of a lipid bilayer, that is why they're capable of fusing with the semipermeable membrane. This fusion between vesicles and the semipermeable membrane facilitates the transport of each in and out of the cell.
Endocytosis may be a form of transport that moves particles, like massive molecules, components of cells, and even whole cells, into a cell. There are totally different forms of endocytosis, however they all share a standard characteristic: the cell membrane of the cell invaginates, forming a pocket round the target particle. This leads to the substance being contained in a newly formed intracellular vesicle made from the cell membrane.
