[Arrhenius diagrams of respiratory enzymes of liver mitochondria from bass (Morone labrax)].
Arrhenius plot of glutamate, succinate and ascorbate+TMPD oxidation in bass liver mitochondria show a break at different temperatures. Above the break activation energies (Ea) of the three enzymes. Above the break activation energies (Ea) of the three enzymes examined are similar and comparable with literature data in poikilotermic and homeothermic animals. Below the break the Ea are again comparable with poikiloterm and homeotherm ones except for succinate-oxidase whose Ea is surprisingly higher. The data are suggested to be due to the features of the enzymes or to the microenvironmental physical state.
