Detailed explanation-1: -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.

Detailed explanation-2: -Exocytosis occurs when a cell produces substances for export, such as a protein, or when the cell is getting rid of a waste product or a toxin. Newly made membrane proteins and membrane lipids are moved on top the plasma membrane by exocytosis.

Detailed explanation-3: -Exocytosis is a form of bulk transport during which large numbers of molecules are transported out of the cell. In exocytosis, a vesicle (a small, membrane-bound compartment) containing the molecules to be released fuses with the cell membrane, and the contents of the vesicle are expelled.

Detailed explanation-4: -Endocytosis is the process of a cell engulfing and bringing a material or particle from outside the cell inside the cell by enveloping it with the cell membrane. In exocytosis, the plasma membrane becomes fused with vesicles, releasing the contents to the cell’s exterior.
