RESPIRATION AND OXIDATIVE PHOSPHORYLATION O F MITOCHONDRIA FROM TISSUES AND ORGANS O F ANTARCTIC FISH*
Abstract: Research has been carried out on the effect of temperature on the physiological properties of mitochondria isolated from liver, cardiac muscle and encephalon of the Antarctic fish Notothenia neglecta. Mitochondria were obtained in a medium containing 0.25 M mannitol, 0.075 M sucrose, l o 3...
