E)the nongated sodium channel

Question

Quizplus · Accepted Answer

The voltage-gated sodium channel is primarily responsible for the action potential. When a neuron is stimulated, sodium ions rush into the cell through these channels, depolarizing the membrane and causing the action potential to occur. The potassium channels play a role in the repolarization phase of the action potential.
