The action potential is produced by the:
A) movement of neurotransmitters across the ion channels.
B) opening and closing of the nodes in the myelin sheath.
C) reuptake of the neurotransmitters into the vesicles.
D) movement of ions across the membrane of the axon.

Question

Quizplus · Accepted Answer

The action potential is produced by the movement of ions (specifically, sodium and potassium ions) across the membrane of the axon, which changes the electrical charge of the neuron and ultimately results in the propagation of an electrical signal down the length of the axon. The other options listed (A, B, and C) are all related to the activity of neurotransmitters, but they do not directly produce the action potential itself.
