Fig. 5. The effect of mitochondrial respiration in the presence of compound MOPIMP. Compound MOPIMP was added in different concentrations: 0 μM, 5 μM, 10 μM, 50 μM, 100 μM, 200 μM. With the addition of compound MOPIMP, respiration in state 3 (red line) decreased. Respiration in state 4 (green line) and the DNP-uncoupled state (blue line) were stimulated by a low concentration while they were inhibited by a high level of exposure. The respiratory control ratio (RCR = respiration rate of state 3/respiration rate of state 4, black line) also decreased after the addition of MOPIMP. The experiment was repeated thrice.
