The period following an action potential during which a membrane cannot experience another action potential A) is the absolute refractory period B) occurs during the time after the Na⁺ gates have opened until they are restored to their "closed but capable of opening" conformation C) prevents the action potential from spreading back over the part of the membrane where the impulse has just passed D) is the absolute refractory period and occurs during the time after the Na⁺ gates have opened until they are restored to their "closed but capable of opening" conformation E) all of these

Question

Quizplus · Accepted Answer

The absolute refractory period is when the Na+ channels are inactivated and cannot reopen, preventing another action potential. This period ensures unidirectional propagation of the action potential.
