Aim: To investigate on the activity of catalase. Introduction Catalase, an enzyme found in many different tissues, catalyses the equipment failure of henry peroxide into peeing and oxygen. 2H₂O₂ → 2H₂O + O₂ atomic number 1 peroxide is a deadly substance that can be formed during aerobic respiration and catalase removes this product. The activity of catalase can be measured by determination the rate of oxygen push button from hydrogen peroxide. Minced murphy provides a suitable source of catalase and the pH is varied in this prove using citric blistery-sodium orthophosphate raw sienna solutions at pH values of 4.4, 5.2, 6.5, 7.5 and 9. Hypothesis: As the value of pH increases, the come of oxygen increases up to a point where the tot decreases. This is because the busy site is denatured and the 3 dimensional anatomy is altered. weapon: Citric acid-sodium phosphate buffer solutions of pH 4.4, 5.2, 6.5, 7.5 and 9 Hydrogen peroxide solution Potato 10ml and 100ml quantity piston put up Stopwatch Stand and clamp Water bucket pH paper, pH cadence and pH probe connected to data logger.
