[Effect of the outer mitochondrial membrane fraction on mitoplast respiration].
Additions of the fraction of outer mitochondrial membranes to the mitoplast suspension is shown to bring about an increase of the ADP-stimulated respiration rate, indices of respiration control and uncoupled respiration. This effect is not a result of the cytochrome c presence in the fraction of outer membranes. In the glycerol-containing medium which causes dissociation of intermembrane contacts the coupling effect of outer membranes on mitoplast respiration is not revealed. It is concluded that the outer membrane in contact with the inner one takes part in realization of the mitochondrial coupling.
