Summary of respiratory control (RC) measured by conventional oximetry with a Clark-type electrode in isolated mitochondria. Oxygen consumption was analyzed with substrates for complex I (glutamate/malate) and complex II (succinate + rotenone) by measuring the slopes of state 4 and state 3, as shown in Figure 2. Values represent median ± SD; ^∗p < 0.05 (n = 4).
