What is caused by the inability of Na+ ion channels to open for several milliseconds after their inactivation?
A)hyperpolarization
B)depolarization
C)termination
D)a refractory period
E)an action potential

Question

Quizplus · Accepted Answer

The inability of Na+ ion channels to open for several milliseconds after their inactivation causes a refractory period. During this period, it is impossible to generate another action potential, no matter how strong the stimulus. This ensures that each action potential is separate and prevents them from overlapping.
