Sodium Pump in T-Tubules of Frog Muscle Fibers

Part of the Series of the Centro de Estudios Científicos de Santiago book series (SCEC)

Abstract

It is well known that in the cytosol of most cells the high concentration of K+ ([K +] i ) and the relatively low concentration of Na+ ([Na+] i ) are kept constant in spite of their electrochemical gradients, which promotes the loss of K+ and the gain of Na+. The steadiness of [K +], and [Na+] i , is maintained by a metabolic energy-dependent active transport process first proposed by Dean(1) in skeletal muscle and known as the Na+ pump (Dean coined the name) or more properly as the Na + /K + pump.
