Once an action potential is initiated, there is a period that must elapse before Na⁺ channels can be activated again to generate another action potential.This is called the _______ period. A) membrane depolarization B) membrane hyperpolarization C) refractory D) undershoot E) after-hyperpolarization

Question

Quizplus · Accepted Answer

During the refractory period, the membrane is unresponsive to a new stimulus due to the inactivation of the Na⁺ channels, which are responsible for generating an action potential. This period allows for the recovery of the ion channels and the restoration of the resting membrane potential.
