Sodium-potassium pump

The sodium-potassium pump is a vital protein found in cell membranes that helps maintain the balance of sodium and potassium ions inside and outside of cells. It works by using energy to move sodium ions out of the cell while bringing potassium ions in. This process creates a concentration gradient essential for various cellular functions, including nerve signal transmission and muscle contraction. By regulating these ion levels, the pump ensures that cells can perform their functions properly and maintain overall stability in the body's systems.
