Fig 2. Complex enzyme maximum activity is not consistently altered by hypothermic experimental temperatures.

(A-F) Citrate synthase (A), and complexes I (B), II (C), III (D), IV (E), and V (F) V_max from homogenized whole mouse brain assayed at physiological temperature (37°C; white bars) or a hypothermic temperature (28°C; black bars). Data are mean ± SEM. Numbers in parenthesis indicate the number of samples assayed from individual animals. Asterisks (*) indicate significant differences between physiological and hypothermic temperatures (p < 0.05; see Results section for statistical tests).
