Definition of EXOCYTOSIS: the release of cellular substances (such as secretory products) contained in cell vesicles by fusion of the vesicular membrane with the plasma membrane and subsequent release of the contents to the exterior of the cell… See the full definition
Exocytosis | Meaning of Exocytosis by Lexico: What does exocytosis mean? exocytosis is defined by the lexicographers at Oxford Dictionaries as A process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane…
My botty best at summarizing from Wikipedia: exocytosis is a form of active transport and bulk transport . a cell secretes molecules out of the cell by secreting them through an energy-dependent process . most chemical substances important to cells are large neurotransmitters are typically released from synaptic vesicles into the cleft via exocytosis . they can also be released via reverse transport through membrane transport proteins . cells can insert membrane proteins, vesicular exocytosis in prokaryote gram negative bacteria is a third mechanism . it is the latest finding in eukaryotic cell phenomenon . the periplasm is pin Golgi apparatus does not require ATP to transport proteins . vesicles come into contact with tethering factors that can restrain them . interactions likely to be involved in concentrating synaptic ve Tethered vesicles are also involved in regular cell’s transcription processes . in other cell types, whose secretion is constitutive, there is no priming . the merging of donor and acceptor substances within the vesicle are released into the exterior . this might be waste products or toxins, or signaling molecules like hormones or neurotransmitters . the side of the protein that was facing the inside of some synaptic vesicles are recycled without a full fusion into the membrane (kiss-and-run fusion) others require a complete reformation from the membrane by a specialized complex of proteins
