Activities of the electron transport chain enzymes of the mitochondrial fractions from control and CR mice. A, Complex I activities; B, Complex II activities; C, Complex III activities; D, Complex IV activities. All activities were expressed as μmol/min/mg protein and presented as mean ± SEM (n = 6). Bars within a group, and between groups, that do not share the same letter are significantly different (P < 0.05). The symbol (~) is used to indicate a trend towards an increase or a decrease (P < 0.10) when the difference is not significant. Black bar, M1; Gray bar, M3; Light gray bar, M10.
