Reactive Oxygen Species 12-15 mitochondrially encoded cytochrome c oxidase II Homo sapiens 68-74 14599481-14 2003 In conclusion, lysosomes are sites of cytotoxic ROS formation with redox transition metals (CuII, CrVI, NiII, CoII) whereas mitochondria are the ROS sites for non-redox or poor redox cycling transition metals (CdII, HgII, AsIII). Reactive Oxygen Species 48-51 mitochondrially encoded cytochrome c oxidase II Homo sapiens 110-114
