Question

Quizplus · Accepted Answer

Na+ entering the cell will cause depolarization, as the positive charge will increase the voltage inside the cell, moving it closer to the threshold for an action potential.

Answer: E
 This answer is possible because the influx of Na+ could cause a depolarization that may lead to either a hyperpolarization (if K+ channels open and K+ leaves the cell) or repolarization (if Na+ channels close and K+ channels open). The resting membrane potential would only be affected if there were a change in the movement of K+ out of the cell.
