A change in a membrane potential from -70 mV to -60mV is an example of
A)depolarization
B)hyperpolarization
C)polarization
D)repolarization
E)zero potential

Question

Quizplus · Accepted Answer

Depolarization is the process by which the membrane potential becomes less negative, or more positive. A change in membrane potential from -70mV to -60mV represents a shift towards a more positive potential, which is characteristic of depolarization. Hyperpolarization would be characterized by a shift towards a more negative potential, polarization refers to the resting potential of the membrane, repolarization involves the return of the membrane potential to its resting state after depolarization, and zero potential indicates that there is no electrical potential difference across the membrane.
