The sodium-potassium pump moves sodium ions (Na⁺) out of the cell and potassium ions (K⁺) into the cell. This pump is crucial for maintaining the electrochemical gradient across the cell membrane, which is essential for various cellular functions, including nerve impulse transmission and muscle contraction. Typically, the pump exchanges three sodium ions out for two potassium ions in, consuming ATP in the process.
