During the absolute refractory period, the voltage-gated Na⁺ channels are not capable of opening again in response to another triggering event.

Question

Quizplus · Accepted Answer

During the absolute refractory period, the voltage-gated Na⁺ channels are inactivated and cannot be opened again until they transition back to their closed or resting state, making it impossible for another triggering event to stimulate action potential during this time.
