Which of the following is a direct result of depolarizing the presynaptic membrane of an axon terminal?
A)Voltage-gated calcium channels in the membrane open.
B)Synaptic vesicles fuse with the membrane.
C)Ligand-gated channels open,allowing neurotransmitters to enter the synaptic cleft.
D)An EPSP or IPSP is generated in the postsynaptic cell.

Question

Quizplus · Accepted Answer

Depolarizing the presynaptic membrane causes voltage-gated calcium channels to open, allowing calcium ions to enter the axon terminal, which is a crucial step in neurotransmitter release.
