Exocytosis is a procedure by which a cell transports secretory items through the cytoplasm to the plasma film. Secretory items are bundled into transport vesicles. In exocytosis, the one that fuses with the membrane package is the cell membrane. The membrane is transported to the cell membrane and the water molecules are released into the extracellular environment.
