Definition of exocytosis in English:
exocytosis
nounˌɛksəʊsʌɪˈtəʊsɪsˌeksōsīˈtōsəs
mass nounBiology A process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane.
Example sentencesExamples
- Membrane fusion is a key event in many essential cell processes, such as exocytosis, endocytosis, membrane recycling, protein sorting and transport, fertilization, and cell division.
- Urea and lysozyme secretion were dose dependent in all groups, suggesting that serous cell exocytosis was one source of urea after neural stimulation.
- Synaptic nerve terminals and neuroendocrine cells rely on continuous vesicle cycling to support sustained exocytosis and transmitter release.
- Planar-supported membranes provide an interesting and very useful new approach to study the complex molecular machinery of exocytosis and membrane fusion.
- In the studies cited, only the intensity of fluorescence was used to observe the metabolism, exocytosis and phagocytosis of cells.
Derivatives
adjectiveˌɛksəʊsʌɪˈtɒtɪk
Biology Hormones are released from neuroendocrine cells by passing through an exocytotic pore that forms after vesicle and plasma membrane fusion.
Example sentencesExamples
- Can similar conformational transitions occur in vivo, for example, during exocytotic swelling of secretory granules or in a stretched fibronectin matrix?
- In addition to factors regulating the fusion of exocytotic vesicles with the plasma membrane, postfusion events have attracted broad scientific interest.
- Although the mechanisms of acidification remain uncertain, the idea that pH changes may facilitate secretion by affecting exocytotic proteins, making them more fusogenic, has also been considered.
- Release of neurotransmitters and hormones from cells involves exocytotic fusion of secretory vesicles with the plasma membrane.
