If a resting axon increases its permeability to sodium ions:
A) the outward movement of sodium ions will decrease.
B) the membrane potential will hyperpolarize.
C) the membrane potential will repolarize.
D) the influx of sodium ions will increase and the membrane will depolarize.

Question

Quizplus · Accepted Answer

Increasing the permeability to sodium ions allows more sodium to enter the axon, leading to depolarization of the membrane potential.
