Regulated exocytosis is a process in which the membranes of cytoplasmic organelles fuse with the plasma membrane in response to stimulation. 调节胞外分泌的过程中,膜的细胞质融合与细胞质膜响应刺激。 www.syyxw.com 4. The Golgi apparatus provides polysaccharide-filled vesicles that deposit wall material...
This process of exocytosis is initiated by an increase in the intracellular Ca2+ concentration caused by the opening of presynaptic Ca2+ channels. Because the intracellular Ca2+ signal that drives vesicle fusion is an extremely short-lived microdomain signal close to open Ca2+ channels which cannot ...
Exocytosis is the process by which cytoplasmic secretory vesicles fuse with the cellular membrane, releasing contents to the extracellular space. Latest Research and Reviews Septin5 deletion enhances β-cell exocytosis by releasing microtubule-tethered insulin granules onto plasma membrane Septins are the...
from Chapter 4 / Lesson 5 214K Cells can engulf their surroundings through a special process called endocytosis, folding its membrane inward to consume its surroundings. It can also get rid of the leftovers through exocytosis. Explore the strange world of cell consumption in this l...
exocytosis Medical Encyclopedia Wikipedia ex·o·cy·to·sis (ĕk′sō-sī-tō′sĭs) n.pl.ex·o·cy·to·ses(-sēz′) A process of cellular secretion or excretion in which substances contained in vesicles are discharged from the cell by fusion of the vesicular membrane with the outer ce...
Endocytosis is an invagination of the cell surface to form an intracellular membrane-bounded vesicle containing extracellular fluid67; exocytosis may be considered the opposite process—that is, fusion of a plasma membrane–bounded vesicle to the cell surface, followed by release of its contents. Endo...
Exocytosis is a form of active transport and bulk transport in which a cell transports molecules (e.g., neurotransmitters and proteins) out of the cell by secreting them through an energy-dependent process. In exocytosis, membrane-bound secretory vesicles are ...
Endocytosis is the process by which substances are engulfed into the cell. Exocytosis is the reverse; the process by which substances are released from the cell. In this article, we will discuss the processes of endocytosis and exocytosis, and we will consider clinical conditions which result from...
Substances destined for export from eukaryotic cells are packed into membrane vesicles (or granules). Exocytosis is the process of fusion of these vesicles with the plasma membrane whereby soluble components from the vesicle interior are released outside
Exocytosis is a process that occurs when a cell moves large materials from inside the cell to the outside of the cell using small spheres of membrane called vesicles. This process is a form of active transport, meaning it uses energy. During exocytosis, vesicles are formed in the Golgi ...
