MCAT Bio/Biochem Questions and Answers | Latest Version | 2024/2025 | 100% Verified Explain the role of the sodium-potassium pump in maintaining resting membrane potential. The sodium-potassium pump actively transports three sodium ions out of the cell and two potassium ions into the cell, helping to maintain the resting membrane potential by creating an electrochemical gradient. Describe the process of oxidative phosphorylation in cellular respiration. Oxidative phosphorylatio...
