Cells have enzymes that help regulate chemical reactions. Enzymes need a substrate to act on. In this reaction, catalase is the enzyme that acts on hydrogen peroxide, the substrate, and breaks it down to water and oxygen. In this way, catalase protects the cells from the potential oxidative damages of hydrogen peroxide.
