Question

define Exocytosis and vesicles?​

Answer 1

Answer:

Exocytosis is the process of moving materials from within a cell to the exterior of the cell. ... In exocytosis, membrane-bound vesicles containing cellular molecules are transported to the cell membrane. The vesicles fuse with the cell membrane and expel their contents to the exterior of the cell.

Answer 2

• Exocytosis is the process by which a large amount of molecules are released; thus it is a form of bulk transport. In exocytosis, membrane-bound secretory vesicles are carried to the cell membrane, and their contents (i.e., water-soluble molecules) are secreted into the extracellular environment.

• In cell biology, a vesicle is a structure within or outside a cell, consisting of liquid or cytoplasm enclosed by a lipid bilayer. Vesicles form naturally during the processes of secretion (exocytosis), uptake (endocytosis) and transport of materials within the plasma membrane.
