Abstract

The effects of catecholamines on the oxidative phosphorylation of mitochondria and superprecipitation of myosin B was studied. Mitochondrial oxidative phosphorylations was inhibited by catecholamines. But super-precipitation of myosin B was activated by isoproterenol when the superprecipitation was inhibited by the microsomal fraction.
