Mitochondrial inner membrane complex activity assay. The activities of complex I in panel (a), complex II in panel (b), and complex IV in panel (c) were tested by treatments with the inhibitors rotenone, malonate, and sodium azide, respectively. Error bars indicate the SDs of the means (n = 3). Significant differences were determined with the student’s t-test (***p < 0.005)
