title: The effect of age on mitochondrial enzymes and respiration.
abstract: There was no significant difference between the levels of cytochrome oxidase and malate dehydrogenase in whole liver homogenates or in mitochondria isolated from the livers of 6-month-old and 30-month-old C57/BL mice. Little change with age was found in the cytochemical localisation of either enzyme. There were no significant changes in endogenous, state III or state IV respiration of mitochondria isolated from the livers of young and old mice.
