Quizplus · Accepted Answer

In Step 3 of the process described, the vesicle containing the neurotransmitter migrates to the cell membrane and releases its contents into the synaptic cleft through exocytosis. This is a key step in neurotransmission, allowing the neurotransmitter to then diffuse across the synaptic cleft and interact with receptors on the postsynaptic neuron.
