E) leak channels and ion pumps

Question

Quizplus · Accepted Answer

The development of resting membrane potential is primarily due to the action of ion pumps and leak channels. Ion pumps actively pump ions (such as sodium and potassium) against their concentration gradient, which creates an electrochemical gradient. Leak channels allow ions to passively move through the membrane, down their concentration gradient, which also contributes to the resting membrane potential. Gated channels, on the other hand, are involved in generating action potentials, but do not play a significant role in maintaining the resting membrane potential. Therefore, the correct answer is E, as it includes the two components responsible for the development of the resting membrane potential.
