Verified
An action potential includes
A) depolarization only.
B) repolarization only.
C) depolarization and repolarization.
D) resting potential and depolarization.
E) resting potential and repolarization.
Depolarization
A process in which the electrical charge of a cell's membrane becomes less negative, triggering an action potential in neurons and muscle cells.
Repolarization
The process by which a neuron or muscle cell returns to its resting negative membrane potential after being depolarized.

Final Answer :
C
Explanation :
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.
