Investigating the effect of PH on the activity of the enzyme catalase. Hydrogen Peroxide will be the source of substrate, and the catalase enzyme breaking down the hydrogen peroxide will be from potato's. The products formed when H202 is broken down will be water and oxygen. The word equation and balanced equation for the reaction would be: (catalyse) Hydrogen Peroxide --> Water + Oxygen 2H20 2 --> 2H20 + 02 Hydrogen Peroxide bond - Catalase Catalase is a common enzyme found in all living organisms. Its function is to catalyze the decomposition of hydrogen peroxide to water and oxygen. Catalase has one of the highest turnover rates of all enzymes; one molecule of catalase can convert millions of molecules of hydrogen peroxide to water and oxygen per second. The optimum pH for catalase is around neutral (pH 7.0). It is a protein of four polypeptide chains, each over 500 amino acids long. All...
