What is NOT true of the relative refractory period?
A)Na+ channels are inactivated
B)many Na+ channels are returning to a closed state
C)K+ is moving out of the axon through its open channels
D)a strong stimulus could cause a depolarization

Question

Quizplus · Accepted Answer

During the relative refractory period, Na+ channels are not inactivated; instead, they are transitioning back to their resting state, making it possible, though difficult, for another action potential to be initiated if a sufficiently strong stimulus is applied.
