Perri Oldfield INVESTIGATION OF THE EFFECT OF PH ON THE ACTIVITY OF CATALASE Introduction: Catalase is an enzyme that can be found in different tissues. It catalyses the breakdown of hydrogen peroxide into water and oxygen, the chemical equation is below: 2H 0 - 2H + O Hydrogen peroxide is formed during aerobis respiration and is a toxic substance. Catalase removes it's product. In our investigation we are looking to find the approximate optimum PH for the activity of catalase. We can measure the amount of this activity by finding the rate if oxygen release during the reaction between hydrogen peroxide and catalase. BACKGROUND INFORMATION ON ENZYMES: Enzymes are protein catalysts, which speed up reactions in organisms. Without enzymes reactions in cells would be so slow that nothing would happen. There are two different types of enzymes: Intracelllar: enzymes inside cells where metabolism is controlled Extracelluar: enzymes produced by cells but work outside the cells. (eg digestive enzymes). ...
