A cell cannot produce an action potential:
A) during the relative refractory period.
B) during the absolute refractory period.
C) during the intermediate refractory period.
D) None of the answers is correct.

Question

Quizplus · Accepted Answer

The absolute refractory period is the time during which a second action potential cannot be produced, regardless of the strength of the stimulus. This is because the voltage-gated sodium channels that are responsible for depolarization are already inactivated. Therefore, the cell cannot produce an action potential during this time.
