Document Summary
What are the major forms of reaction oxygen and how are they formed (see figure. 6. 25): what reactions are catalyzed by the two enzymes superoxide dismutase and. Catalase. role of cytochrome oxidase in production of ros. Donate 4 e at a time to oxygen, not one at a time, so you can get complete reduction of o2 to h2o in one step. Since oxygen is the terminal e acceptor, there must be 4 e donated at once. role of quinone pool in production of ros. There is so much oxygen in the matrix that some of those electrons leak from the q pool and react with oxygen to form superoxide (the one electron reduction of oxygen role of quinone pool in production of ros. They dont live as long if theres a mutation to the cytochrome complex bc of the increased ros. mutants are very susceptible to ros.
