... Here’s an example: Hydrogen peroxide (H2O2) is produced naturally inside many of your cells. The trouble is that it is very toxic to us. To deal with this, we produce an enzyme called catalase, which serves to break down hydrogen peroxide into a couple of pretty harmless substances: 2H2O2 2H2O + O ...
