Enzyme Mechanism for the Active Transport of Sodium and Potassium Ions in Animal Cells

Abstract

SEVERAL mechanisms have been proposed which link the active transport of Na+ and K+ to the hydrolysis of ATP. These suggest either diffusion across the membrane of specific carriers of Na+ and K+1–3, or the formation of a phosphorylated membrane derivative4–7. Evidence in favour of these mechanisms is not, however, conclusive, and this article presents a new model for transport of Na+ and K+, the experimental verification of which may be possible.
