But either one of these two enzymes basically catalyze the following two step process. So in process one we have the oxidized version of this mutate that reacts with a single superoxide ion. So it essentially releases a diatomic oxygen and it keeps a single electron so that we oxidize or we reduce it into the reduced this mutase version. Now, the reduced dismutase then reacts with another superoxide anion as well as with two H plus ions. And this allows us to basically oxidize this, reduce this mutate back into the oxidized version. So we regenerate that enzyme and we also form this hydrogen peroxide.
