Chapter 39, Problem 5TYK

The major role of the Na⁺/K⁺ pump is to:

a. cause a rapid firing of the action potential so the inside of themembrane becomes momentarily positive.

b. decrease the resting membrane potential to zero.

c. hyperpolarize the membrane above resting value.

d. cause an action potential to enter a refractory period.

e. maintain the resting membrane potential at a constantnegative value.
