Abstract
Na+ transport was measured in the Ehrlich mouse ascites tumor cell by isotopic and chemical methods. Evidence for an initial, rapidly exchanging Na+ compartment was found in addition to a slower compartment. Net Na+ efflux might constitute less than half the total efflux. Influx of Na+ decreased while intracellular Na+ was falling, demonstrating a dependence of Na+ influx on intracellular Na+ content. Taken together, the data provide evidence for a component of Na+ transport which is mediated but not active.
