An action potential includes
A) depolarization only.
B) repolarization only.
C) depolarization and repolarization.
D) resting potential and depolarization.
E) resting potential and repolarization.

Question

Quizplus · Accepted Answer

An action potential involves both depolarization, which is the influx of positively charged ions into the cell, followed by repolarization, which is the restoration of the resting potential by the efflux of those positively charged ions. Therefore, both A and B are incorrect. While D and E include some aspects of the action potential, they do not encompass the full process of depolarization and repolarization.
