A shift of the resting transmembrane potential toward 0 mV is called
A)depolarization.
B)repolarization.
C)hyperpolarization.
D)non-polarization.
E)hypopolarization.

Question

Quizplus · Accepted Answer

Depolarization is a shift of the resting transmembrane potential toward 0 mV. This occurs when positive ions (such as Na+) enter the cell, making it more positive inside, and bringing the membrane potential closer to the threshold for an action potential.
