During synaptic transmission,_______ would cause the ion channels to open,and _______ would cause the synaptic vesicles to fuse with the terminal membrane.

B)enzymes; an action potential
C)an action potential; calcium
D)calcium; enzymes

Question

Quizplus · Accepted Answer

During synaptic transmission, an action potential would cause depolarization of the presynaptic membrane, leading to the influx of calcium ions. The increased levels of calcium ions would then trigger the fusion of the synaptic vesicles with the terminal membrane, causing the release of neurotransmitters into the synaptic cleft. Therefore, option C, where an action potential would cause ion channels to open, and calcium would cause synaptic vesicles to fuse with the terminal membrane, is the correct answer.

During Synaptic Transmission,_______ Would Cause the Ion Channels to Open,and
