Exocytosis. Exocytosis is a process in which an intracellular vesicle (membrane bounded sphere) moves to the plasma membrane and subsequent fusion of the vesicular membrane and plasma membrane ensues. Many cellular processes involve exocytosis. For example a few of the processes that use exocytosis are:secretion of proteins like enzymes, peptide hormones and antibodies from cells. turnover of plasma membrane. release of neurotransmitter from presynaptic neurons. placement of integral membrane proteins.any cellular processes involve exocytosis. For example a few of the processes that use exocytosis are: secretion of proteins like enzymes, peptide hormones and antibodies from cells. turnover of plasma membrane.
