Abstract: Acute cooling of rats led to stimulation of NAD+-dependent isocitrate dehydrogenase (ICDH), succinate dehydrogenase (SDH) and NAD(P)+-transhydrogenase (TH) but did not affect the NADP+-ICDH activity in liver, heart and skeletal muscle mitochondria. After pretreatment of the animals with propranolol the stimulating effect was decreased, thus suggesting that endogenous catecholamines and beta-adrenoreceptors are of importance in activation of NAD+-ICDH, SDH and TH. The effects of cooling, noradrenaline and cAMP did not summarize. Role of catecholamines in stimulation of mitochondrial oxidative enzymes under conditions of cooling is discussed.
