Neurotransmitters are released from axon terminals via ________.
A) osmosis
B) active transport
C) diffusion
D) exocytosis

Question

Quizplus · Accepted Answer

Neurotransmitters are released from axon terminals through exocytosis, which is the process in which the neurotransmitter-containing vesicles fuse with the membrane of the axon terminal and release the contents into the synaptic cleft. This is an active process that requires energy and specific proteins. Osmosis and diffusion are passive processes that do not involve vesicle fusion or energy expenditure. Active transport refers to the movement of molecules against a concentration gradient, and is not involved in the release of neurotransmitters from axon terminals.
