Quizplus · Accepted Answer

The Na-K pumps maintain the resting membrane potential by actively transporting three sodium ions out of the cell for every two potassium ions that are pumped in. This creates a concentration gradient of sodium and potassium ions across the cell membrane, which drives the movement of sodium and potassium ions through the leaky sodium and potassium channels, respectively.
