OXIDATION OF EXTRAMITOCHONDRIAL DIPHOSPHOPYRIDINE NUCLEOTIDE BY VARIOUS TISSUES OF THE MOUSE.

Exogenous reduced diphosphopyridine nucleotide was not oxidized by mitochondria but by cytoplasmic hydrogen-accepting systems catalyzed by lactic, alpha-glycerophosphate, and malic dehydrogenases. The three enzymes were found in all tissues of the mouse; the amount of activity of each enzyme differed in the various tissues, however. It is suggested that each tissue has a unique pattern for oxidation of extramitochondrial diphosphopyridine nucleotide.

The effect of temperature on oxidative phosphorylation with insect flight muscle mitochondria.

The effect of different temperatures on the biochemical activity and morphology of insect flight muscle mitochondria was examined. It was found that respiration and phosphorylation have the same thermal response at temperatures of 25 degrees C. and below. The energy of activation for both systems is approximately 12,300 calories. Oxidation and phosphorylation can be uncoupled effectively by temperature, for at temperatures above 25 degrees C. there is more rapid heat inactivation of phosphorylation. This is evident from reduced P/O values as well as from morphological deterioration in the mitochondrial population. The thermal response of both this sarcosomal enzyme system and the respiration in the living fly are quantitatively similar.
