During the absolute refractory period, the Na⁺ gates 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 already in an inactive state and cannot be opened, regardless of the strength of the stimulus. This is to prevent any premature or additional depolarization of the cell, ensuring that the action potential propagates in one direction and lasts for a specific amount of time.
