The rapid change in polarization that occurs when the electrical charge is reversed across the cell membrane so that the inside of each cell is positively charged is referred to as:
A)repolarization.
B)polarization.
C)action potential.
D)excitability.

Question

Quizplus · Accepted Answer

The rapid change in polarization described in the question is the specific change that characterizes an action potential. Repolarization refers to the return to the resting state after an action potential, polarization refers to the unequal distribution of charges between the inside and outside of a cell membrane that allows for the maintenance of a resting potential, and excitability refers to a cell's ability to respond to a stimulus that triggers an action potential.
