The effect of inorganic phosphate on sodium fluxes in dog red blood cells.


The effect of extracellular inorganic phosphate on Na+ movements in dog red blood cells has been studied. As the phosphate concentration is increased from 0 to 30 mM, Na+ efflux increases by 2- to 3-fold and Na+ influx increases approximately 2-fold. This enhancement of Na+ fluxes by phosphate can be prevented by the addition of iodoacetate (1 mM), an… (More)
