Sodium-dependent sugar transport systems involve the function of membrane components that couple the transmembrane flow of Na+ to the concomitant flow of certain sugar molecules. The coupling stoichiometry between Na+ and sugar fluxes via these systems must be measured under conditions in which the membrane potential does not change due to the induction of transport or during the interval of flux measurement. This can be accomplished by utilizing gradients of highly permeant ions (NO-3 and K… CONTINUE READING
