The influx of positive charges makes the membrane potential more positive and is known as:
A)polarization.
B)hyperpolarization.
C)repolarization.
D)depolarization.

Question

Quizplus · Accepted Answer

Depolarization is the correct choice as it refers to the process of the membrane potential becoming more positive due to the influx of positive charges, such as sodium ions. Polarization refers to the initial resting state of the membrane with a negative charge inside. Hyperpolarization occurs when the membrane potential becomes even more negative than the resting potential, and repolarization is the return of the membrane potential to its resting state after depolarization.
