The sodium-potassium pump, also known as Naâº/Kâº-ATPase, is an enzymatic complex located in the plasma membrane of cells. It actively transports three sodium ions out of the cell and two potassium ions into the cell, utilizing ATP in the process. This transport is crucial for maintaining the electrochemical gradients across the cell membrane, which are essential for functions such as nerve impulse transmission and muscle contraction.
