When more action potentials arrive at the axon terminal, how are neurotransmitters affected?
A) More molecules are released into the synapse.
B) Different molecules are released into the synapse.
C) Fewer molecules are released into the synapse.
D) There is no effect-all signals are identical.

Quizplus · Accepted Answer

When more action potentials arrive at the axon terminal, more calcium ions flow into the terminal causing more synaptic vesicles to fuse with the membrane and release more neurotransmitter molecules into the synapse. Therefore, more molecules are released into the synapse.
