  2. Cytosis - Wikipedia

    Mechanism of clathrin-dependent endocytosis. Clathrin-coated pits in endocytosis: The membrane of the cell invaginates using the protein clathrin. The clathrin uses actin to pull together the sides of the plasma membrane and form a vesicle inside the cellular cytosol. Receptor-mediated endocytosis Receptor-mediated endocytosis is a mode of ...

    en.wikipedia.org/wiki/Cell_membrane

    Endocytosis requires energy and is thus a form of active transport. Exocytosis: Just as material can be brought into the cell by invagination and formation of a vesicle, the membrane of a vesicle can be fused with the plasma membrane, extruding its contents to the surrounding medium. This is the process of exocytosis.

  4. Exocytosis - Wikipedia

    en.wikipedia.org/wiki/Exocytosis

    Exocytosis and its counterpart, endocytosis, are used by all cells because most chemical substances important to them are large polar molecules that cannot pass through the hydrophobic portion of the cell membrane by passive means. Exocytosis is the process by which a large amount of molecules are released; thus it is a form of bulk transport.

  5. Kiss-and-run fusion - Wikipedia

    en.wikipedia.org/wiki/Kiss-and-run_fusion

    Kiss-and-run fusion is a type of synaptic vesicle release where the vesicle opens and closes transiently. In this form of exocytosis, the vesicle docks and transiently fuses at the presynaptic membrane and releases its neurotransmitters across the synapse, after which the vesicle can then be reused.

    Coat proteins can also function to bind to various transmembrane receptor proteins, called cargo receptors. These receptors help select what material is endocytosed in receptor-mediated endocytosis or intracellular transport. There are three types of vesicle coats: clathrin, COPI and COPII. The various types of coat proteins help with sorting ...

  7. Vesicle fusion - Wikipedia

    en.wikipedia.org/wiki/Vesicle_fusion

    Vesicle fusion is the merging of a vesicle with other vesicles or a part of a cell membrane.In the latter case, it is the end stage of secretion from secretory vesicles, where their contents are expelled from the cell through exocytosis.

  9. Endomembrane system - Wikipedia

    en.wikipedia.org/wiki/Endomembrane_system

    Endocytosis refers to when substances are taken into the cell, whereas for exocytosis substances are moved from the cell into the extracellular space. Material to be taken-in is surrounded by the plasma membrane, and then transferred to a vacuole. There are two types of endocytosis, phagocytosis (cell eating) and pinocytosis (cell drinking). In ...
