Fig. 3. Ratio of mitochondrial rates of pyruvate oxidation to maximal activities of
cytochrome c oxidase (CCO) and citrate synthase (CS) during warm and
cold acclimation. Values are expressed per mU CCO and per mU CS. Data are
means ± S.E.M. When values at a given assay temperature
during each acclimation experiment differ, they are followed by different
letters (P
0.05; ANOVA and Tukey's a posteriori test).
The number of individuals in each experiment is shown in
Table 1.
