Influence of increased environmental temperature on oxidation processes in rat liver mitochondria.
Exposure of rats to elevated temperature of 28 degrees C or 35 degrees C for 3 days six hours daily resulted in a decreased rate of oxidation with succinate or glutamate + malate as substrates, by the mitochondria of liver. The higher decrease was observed in environment temperature of 35 degrees C. There was no change in ADP/O ratio. The activities of NADH: cytochrome c reductase and cytochrome oxidase were stimulated but activities of succinate dehydrogenase and succinate cytochrome reductase were decreased.
