  • Catalase - 2435 Words
    CATALASE Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It catalyzes the decomposition of hydrogen peroxide to water and oxygen. It is a very important enzyme in reproductive reactions. Likewise, catalase has one of the highest turnover numbers of all enzymes; one catalase molecule can convert millions of molecules of hydrogen peroxide to water and oxygen each second. Catalase is a tetramer of four polypeptide chains, each over 500 amino acids long. It...

    An enzyme is a tertiary globular protein. The function of an enzyme is to lower the activation energy of either the creation or breaking apart of a chemical bond. By lowering the activation energy of this process, the reaction of bonding, or in this case breaking apart, is sped up. An enzyme breaks apart the substrate in the active site of the enzyme; this is where the magic happens. Substrate is what is being broken apart by the enzyme. In this case, the enzyme is catalase and the substrate is...
