'''Potassium within cells interacts with [[Sodium - Nutrition|sodium]] outside cells to form a concentration gradient that maintains acid-base balance and facilitates electrical and chemical activity'''. This accounts for its importance in nerve impulses and muscle contraction and its role in normal cardiac function. It is also involved in protein synthesis and the uptake of amino acids. The trans-cellular potassium-sodium gradient is actively maintained by an energy-dependent system that drives cellular pumps responsible for the transport of potassium and sodium ions.
