(noun)

Examples of exocytosis in the following topics:

  • Exocytosis

    • Exocytosis is the process by which cells release particles from within the cell into the extracellular space.
    • Exocytosis is used continuously by plant and animal cells to excrete waste from the cells.
    • Exocytosis is composed of five main stages.
    • In exocytosis, vesicles containing substances fuse with the plasma membrane.
    • Describe exocytosis and the processes used to release materials from the cell.
  • Viral Exit

    • Another method is by accumulating the virus particles in vesicles and releasing them via exocytosis.
    • Exocytosis is the process where vesicles containing the virus are secreted/excreted out of the infected cell.
  • Synaptic Transmission

    • The synaptic vesicles fuse with the presynaptic axon terminal membrane and empty their contents by exocytosis into the synaptic cleft.
  • Contractile Vacuoles in Microorganisms

    • ., amoeba), cellular wastes, such as ammonia and excess water, are excreted by exocytosis as the contractile vacuoles merge with the cell membrane, expelling wastes into the environment.
  • Components of Plasma Membranes

  • Cell Structure, Metabolism, and Motility

    • Undigested remains ultimately exit the cell via exocytosis.
  • Peripheral Motor Endings

    • This influx of Ca2+ causes neurotransmitter-containing vesicles to dock and fuse to the presynaptic neuron's cell membrane, which results in the emptying of the vesicle's contents (acetylcholine) into the synaptic cleft, a process known as exocytosis.
  • Mechanisms of Hormone Action

    • Hormones exit their cell of origin through the process of exocytosis or other means of membrane transport.
  • Vesicles and Vacuoles

    • Vesicles form naturally during the processes of secretion (exocytosis), uptake (phagocytosis) and transport of materials within the cytoplasm.
  • Double-Stranded DNA Viruses: Pox Viruses

    • In addition, during transit through the cytoplasm, a subset of progeny MVs acquires two additional membrane bilayers, one of which is lost during exocytosis of the particle, to yield the less abundant enveloped virion (EV).
