Detailed explanation-1: -Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell, as s hown in Figure below. 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.

Detailed explanation-2: -Exocytosis is a form of active transport through which large molecules are moved from the interior to the exterior of the cell. Vesicles are packaged within the cell and transported to the cell membrane, where their phospholipid bilayers fuse. This allows the contents to be released outside the cell.

Detailed explanation-3: -Endocytosis and exocytosis are the mechanisms by which cells transport items that are too big to pass through the lipid bilayer of the cell membrane directly into or out of the cell. Exocytosis and endocytosis are two processes that allow large molecules, bacteria, and waste materials to pass through the cell membrane.

Detailed explanation-4: -Exocytosis. Cells must take in certain molecules, such as nutrients, but they also need to release other molecules, such as signaling proteins and waste products, to the outside environment.

Detailed explanation-5: -Exocytosis is defined as the transport and fusion of secretory vesicles with the plasma membrane and the extracellular space. There are three exocytosis pathways that deliver vesicles to the plasma membrane.
