Mitochondrial enzyme activity fitted to the Michaelis–Menten equation. A Activity of NADH: ubiquinone oxidoreductase (complex I) with varying concentrations of NADH, B Activity of NADH: ubiquinone oxidoreductase (complex I) with varying concentrations of ubiquinone. C Activity of succinate dehydrogenase (complex II) with varying concentrations of succinate. D Activity of succinate dehydrogenase (complex II) with varying concentrations of decylubiquinone. E Activity of coenzyme Q: cytochrome c oxidoreductase with varying concentrations of decylubiquinol. F Activity of coenzyme Q: cytochrome c oxidoreductase with varying concentrations of oxidized cytochrome c. G Activity of cytochrome c oxidase (complex IV) with varying concentrations of reduced cytochrome c. Results represent mean and standard error for duplicated or triplicated experiments
