title: Possible mode of action of nitroglycerin on heart mitochondria.
abstract: Nitroglycerin has no effect on the electron transport and oxidative phosphorylation of isolated rabbit heart mitochondria at 5 X 10(-4) M and lower concentrations. However, it diminished the phosphate-induced energy-dependent potassium fluxes through the mitochondrial membrane in both directions; thus it was able to prevent the impairment of the efficiency of oxidative phosphorylation produced by increased ion transport.
