  43. 43. SULIT MOZ@C 2 4551 Answer all questions.Question 1Hydrogen peroxide is a chemical that bubbles when it reacts with a catalase enzyme.Catalase enzyme is an antioxidant enzyme in living cells. Hydrogen peroxide is convertedinto water and oxygen by the catalase enzyme 2H2O2 2H2O + O2An experiment is carried out to investigate the effect of pH on catalase enzyme in potatoes.Bubbling of gases is used to indicate that a reaction is occurring. The rate of reaction isdetermined by measuring the volume of bubbles produced in a unit time. The experiment isconducted as followed:1. Three measuring cylinders, P, Q and R are filled with 3.0 cm3 of hydrogen peroxide.2. 6.0 cm3 of 0.1% hydrochloric acid is added to P, 6.0 cm3 of distilled water is added to Q and 6.0 cm3 of 0.1% sodium hydroxide is added to R.3. pH paper is used to measure the pH value of each tube.4. The potato is cut into three cubes, with the size of 1.0 cm3 each.5. One potato cube is added into each measuring cylinder.6. The volume of bubbles produced in each measuring cylinder is observed after 5 minutes and recorded.7.
