D) transcytosis.
E) exocytosis.

Question

Quizplus · Accepted Answer

Neurotransmitters are released from axon terminals via exocytosis, which involves the fusion of vesicles containing neurotransmitters with the presynaptic membrane of the axon terminal, and the subsequent release of neurotransmitters into the synaptic cleft. This process is initiated by an influx of calcium ions into the axon terminal, which triggers the fusion of the vesicles with the presynaptic membrane.
