Sodium-potassium pump, also known as Na+/K+ pump, is a critical enzyme in the body that maintains the electrochemical gradient across cell membranes. This process is essential for various cellular functions, including nerve impulse transmission, muscle contraction, and maintaining the resting membrane potential. The pump works by transporting three sodium ions (Na+) out of the cell and two potassium ions (K+) into the cell, using ATP (adenosine triphosphate) as an energy source. This active transport mechanism is crucial for the proper functioning of excitable cells, such as neurons and muscle cells. The sodium-potassium pump is composed of two subunits, alpha and beta, and is regulated by various factors, including hormones and intracellular signaling molecules. Dysfunction of the sodium-potassium pump has been linked to several diseases, including hypertension, heart failure, and certain types of cancer. Understanding the mechanisms and regulation of the sodium-potassium pump is an active area of research in the field of cellular and molecular biology.
