Fig. 3. Metabolic enzyme activities of alligators in winter and summer at different
assay temperatures. There were significant differences between seasons and
assay temperatures in all enzymes: (A) lactate dehydrogenase (LDH), (B)
citrate synthase (CS) and (C) cytochrome c oxidase (CCO). Note that
the activity of LDH and CCO does not differ between winter animals at 15°C
and summer animals at 30°C and that CS activity is significantly elevated
at 15°C in winter compared with in summer.
