When an action potential arrives in an axon terminal,synaptic vesicles containing acetylcholine are released by:

Question

Quizplus · Accepted Answer

Synaptic vesicles containing acetylcholine are released by exocytosis, which is the process by which the vesicles fuse with the plasma membrane and release their contents outside the axon terminal. Facilitated diffusion is a passive transport process that involves the movement of molecules across a membrane from an area of high concentration to an area of low concentration with the help of a carrier protein. Osmosis is the movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration. Endocytosis is the process by which cells take in molecules or particles by engulfing them into vesicles formed from the plasma membrane.
