the capacity of the various tumor lines for the reoxidation of cytoplasmic nadh via the malate-aspartate shuttle approaches 20 % of the total respiratory rate of the cells and thus appears to be sufficient to account for the mitochondrial reoxidation of that fraction of glycolytic nadh not reoxidized by pyruvate and lactate dehydrognenase in the cytoplasm .
