Have a little read: ... Introduction Hydrogen peroxide (H2O2) is a toxic, oxidation agent produced during chemical reactions in the body of most living organisms. Examples of reactions are the oxidation of fatty acids and respiration in plants. To combat this, the body also makes the intoxicating enzyme, catalase, which quickly breaks down this chemical into the undisruptive, constructive, and disposable oxygen and water. The enzyme uses hydrogen peroxide as both an electron benefactor and electron receiver. The active site contains an essential haem group (red compound containing iron and forming non-protein part of haemoglobin), which is what attracts the oxygen, which acts as the electron acceptor as part of the hydrogen peroxide, which is capable of reacting as acid and base. Effect of enzyme and substrate temperature on the rate of reaction, a convenient system is provided by the breakdown of hydrogen peroxide into water and oxygen. 2H2O2 ? 2H2O + O2 Found in
