Abstract
Catecholamines activate respiration (\(V_{O_2 }\)) of rat liver mitochondria in vivo and in vitro on high concentrations of pyruvate, 2-oxoglutarate, and succinate. The effect is characteristic equally of free oxidation (state 4) and phosphorylating (state 3) or even dinitrophenol-uncoupled\(V_{O_2 }\). The addition of EDTA and bovine serum albumin did not abolish the effect. Activation of oxidoreductases by catecholamines is postulated.
