So we have an enzyme known as superoxide, this mutates, and an enzyme known as catalase. In addition, we also have many different types of vitamins used by our body that actually allows us to control the amount of these reactive oxygen species that we find inside our cells. So let's begin by focusing on super oxide, this mutate. So this is the enzyme that basically locates and converts superoxide radical species like the one basically discussed right here. So this is the general reaction that basically is catalyzed by super oxide, this mutase. But as we'll see in just a moment, the superoxide, this mutate that is used by ourselves basically carries out a two step process.
