Question

Quizplus · Accepted Answer

The potential difference across the cell membrane, known as the membrane potential, is due to the unequal distribution of cations (positively charged ions) and anions (negatively charged ions) across the membrane. This is maintained by various ion channels and transporters, which allow specific ions to cross the membrane and maintain the electrochemical gradient. The membrane potential is critical for many cellular processes, including nerve impulse transmission and muscle contraction.
