activity of catalase.

Aim: To investigate on the activity of catalase. Introduction Catalase, an enzyme found in many different tissues, catalyses the segmentation of heat content bleach into piddle away and oxygen. 2H₂O₂ → 2H₂O + O₂ atomic number 1 peroxide is a unhealthful substance that can be formed during aerobic respiration and catalase removes this product. The activity of catalase can be measured by conclusion the rate of oxygen print from hydrogen peroxide. Minced murphy provides a suitable source of catalase and the pH is varied in this experiment using citric vinegarish-sodium inorganic phosphate yellowish brown solutions at pH values of 4.4, 5.2, 6.5, 7.5 and 9. Hypothesis: As the value of pH increases, the consider of oxygen increases up to a point where the tot decreases. This is because the wide awake site is denatured and the 3 dimensional anatomy is altered. tool: 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 measure piston sleeping accommodation Stopwatch Stand and clamp Water bucket pH paper, pH cadence and pH probe connected to info logger.
