During the entire course of events from the start of an action potential until the membrane returns to its resting potential, what is the net movement of ions?

Question

Quizplus · Accepted Answer

During an action potential, there is a rapid influx of sodium ions into the cell, which causes depolarization. This is followed by a slower efflux of potassium ions out of the cell, which causes repolarization and eventually hyperpolarization. Therefore, the net movement of ions during an action potential is sodium in and potassium out.
