Endocytosis and exocytosis are the processes by which cells move materials into or out of the cell that are too large to directly pass through the lipid bilayer of the cell membrane. Large molecules, ...

In all eukaryotic cells, the constitutive processes of exocytosis and endocytosis maintain the flow of material to and from the cell surface. In secretory active cells, these processes have to be ...

Nervous system function crucially depends on synaptic vesicle exocytosis and endocytosis at defined areas within the nerve terminal. Exocytosis preferentially occurs at defined release sites within ...
