Mitochondrial respiration and reactive oxygen species in young and age, male and female mice. A Oxygen consumption rates, B H₂O₂ emission, and C oxygen consumption rates normalized to mitochondrial protein content in the indicated respiratory states. All values are reported as means ± SEM. For A and B, the main effects of a 3-way ANOVA are represented on the graph at p < 0.05. For A–C, the main effects of 2-way ANOVA are represented on the graph at p < 0.05. δ p < 0.05, post hoc significance. N = 10/male group, N = 8/female group
