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

Question

Quizplus · Accepted Answer

Increasing the permeability to sodium ions means that more sodium ions will enter the axon, leading to an increase in positive charge and depolarization of the membrane potential.
