Pregunta:

What's membrane fusion mechanism?

Autor: Shay 1vcc



Respuesta:

(1) they recognize each other; (2) their surfaces become closely apposed, which requires the removal of water molecules normally associated with the polar head groups of lipids; (3) their bilayer structures become locally disrupted, resulting in fusion of the outer leaflet of each membrane (hemifusion); and (4) their bilayers fuse to form a single continuous bilayer. The fusion occurring in receptor-mediated endocytosis, or regulated secretion, also requires that (5) the process is triggered at the appropriate time or in response to a specific signal.
