Now, inside eukaryotic cells, the cells of our own body we actually have two forms of super oxide this mutase. One form depends on manganese and the other form depends on copper and zinc atoms. So the manganese containing this mutase is found in the mitochondria of our cells while the copper and zinc dependent this mutase is actually found in the cytoplasm of our body. 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.
