At the synapse,what event must occur before the synaptic vesicles release neurotransmitters?
A)The synaptic vesicles fuse with the presynaptic membrane.
B)The action potential causes voltage-gated channels to release calcium ions.
C)Neurotransmitters cross the synaptic cleft.

E)The neurotransmitters are inactivated by enzymes.

Question

Quizplus · Accepted Answer

The first part of a chain that leads to neurotransmitters crossing the synaptic cleft and binding with postsynaptic receptors is the release of calcium ions caused by the action potential reaching the terminal bouton.
