Question

Quizplus · Accepted Answer

During the relative refractory period, the membrane can respond to a stimulus, but only if it is stronger than the threshold stimulus. This is because the membrane is in a hyperpolarized state, making it more difficult to reach the threshold for depolarization. Therefore, choice C is the correct answer. The absolute refractory period occurs immediately after depolarization, where the membrane cannot respond to any stimulus, and the relative refractory period follows.
