When an Action Potential Arrives at the Axon Terminal, the Voltage-Gated

Multiple Choice

When an action potential arrives at the axon terminal, the voltage-gated calcium channels at the terminal

A) release calcium into the synaptic cleft.
B) actively transport neurotransmitter into the synaptic cleft.
C) open; the influx of calcium causes the vesicles to fuse with the presynaptic membrane and release a neurotransmitter into the synaptic cleft.
D) depolarize the membrane at the axon terminal.
E) cause the membrane receptors to bind the neurotransmitter.
