Abstract: The saturation kinetics of NADH and succinate oxidation for Coenzyme Q (CoQ) has been re-investigated in pentane-extracted lyophilized beef heart mitochondria reconstituted with exogenous CoQ10. The apparent Km' for CoQ10 was one order of magnitude lower in succinate cytochrome c reductase than in NADH cytochrome c reductase. The Km value in NADH oxidation approaches the natural CoQ content of beef heart mitochondria, whereas that in succinate oxidation is close to the content of respiratory chain enzymes.
