Exocytosis is a process by which a cell transports secretory products through the cytoplasm to the plasma membrane.Secretory products are packaged into transport vesicles (membrane-bound spheres).xocytosis is the process by which cargo-laden transport vesicles move through the cytoplasm to the plasma membrane. Once at the plasma membrane two different things can happen. Sometimes the vesicle can dock and wait for a secretion signal. This happens in calcium-dependent (regulated) exocytosis.
