Detailed explanation-1: -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-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: -Vesicle function in endocytosis and exocytosis During bulk transport, larger substances or large packages of small molecules are transported through the cell membrane, also known as the plasma membrane, by way of vesicles – think of vesicles as little membrane sacs that can fuse with the cell membrane.

Detailed explanation-4: -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-5: -Exocytosis is a process for moving large molecules out of the cell to the cell exterior.
