The generation of H2O2 in skeletal muscle mitochondria during the oxidation of NAD-dependent substrates and succinate is initiated by antimycin A but not by rotenone, which points to H2O2 formation at the respiratory chain site between the rotenone and antimycin blocks. The O2-/H2O2 ratio for alpha-ketoglutarate and succinate oxidation is approximately 1.4, which suggests that in skeletal muscle mitochondria H2O2 is predominantly formed via the superoxide radical generation. Heart and skeletal muscle mitochondria appeared to have the similar values of Vmax for H2O2 production; the catalase activity in skeletal muscle mitochondria is much lower. |
