Control of oxidative phosphorylation during insect metamorphosis.
The midgut of the tobacco hornworm (Manduca sexta) is a highly aerobic tissue that is destroyed and replaced by a pupal epithelium at metamorphosis. To determine how oxidative phosphorylation is altered during the programmed death of the larval cells, top-down control analysis was performed on mitochondria isolated from the midguts of larvae before and after the commitment to pupation. Oxygen c...
متن کاملOxidative phosphorylation coupled with the oxidation of alpha-ketoglutarate by heart-muscle sarcosomes.
Ochoa (1944) showed that inorganic phosphate was esterified when a-ketoglutarate was oxidized to succinate by particulate preparations obtained from heart muscle. These particles have been identified with the sarcosomes, the granules in muscle which correspond to mitochondria in other tissues (Cleland & Slater, 1953a, b; see also Harman & Feigelson, 1952). A recent paper (Slater, 1953b) describ...

متن کاملThe 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 tem...
متن کاملRespiratory Enzymes in Oxidative Phosphorylation
In a complex enzymatic sequence the site of action of substrates and inhibitors is clearly marked by the way they affect the steady state concentrations of the components of the system (1). Antimycin A, for example, inhibits respiration in the succinic oxidase system (2) and at the same time increases the steady state reduction of cytochrome b and decreases that of cytochromes c, a, and aa (3)....
