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.
This process is called endocytosis, or the import of molecules and particles into the cell by folding the cell membrane inwards. The prefix 'endo-' means 'within.' During endocytosis, vesicles, or circular buds comprised of membrane, are formed around the substance to be digested.n addition, all the phospholipids and other vesicle membrane components also become part of the cell membrane. This is a great way to refresh the cell membrane with new parts. Exocytosis can also release useful products created by your cell into the extracellular space.
