We report the inhibition of glycerol-3-phosphate- and succinate-dependent oxygen consumption rates by digitonin treatment. Our results show that the inhibition of oxygen consumption rates is recovered by the addition of exogenous synthetic analog of coenzyme Q idebenone (hydroxydecylubiquinone) and cytochrome c. Glycerol-3-phosphate oxidation rate is recovered to 148% of control values, whereas succinate-dependent oxidation rate only to 68%. Our findings might indicate the different mechanism of the electron transfer from two flavoprotein-dependent dehydrogenases (glycerol-3-phosphate and succinate dehydrogenases) localized on the outer and inner face of the inner mitochondrial membrane, respectively
