Web736 Words. 3 Pages. Open Document. Grade 12 Biology (SBI 4U1) Nicole Mikulis. Unit: Biochemistry Sept 14 2012. Lab: Effect of temperature and pH on catalase activity. BACKGROUND. Catalase is an enzyme that detoxifies chemicals that might harm the cell such as hydrogen peroxide (H2O2). The enzyme breaks H2O2 into water and oxygen. WebThe structure and function of enzymes is a central theme in cellular and molecular biology. In this laboratory exercise, a crude cell extract is prepared from potatoes. Activity of the enzyme, catalase [which catalyzes the reaction 2H 2 O 2 (l) → 2H 2 O (l) + O 2 (g)], is then studied using a simple assay for O 2. To conduct the assay, a ...

WebIn this core practical activity students plan and carry out an investigation into the effect of temperature on the rate of an enzyme-catalysed reaction using catalase from peas. Catalase breaks down hydrogen peroxide (H2O2) to form water and oxygen. It is a convenient enzyme to use, as it is relatively easy to WebThis study aimed to investigate that rapid high-temperature treatment (RHT) at an appropriate temperature could accelerate callus formation by effectively promoting the …
Webeffect of temperature on the rate at which the enzyme works by measuring the amount of oxygen evolved over a period of time. The experiment was carried out varying the temperature and recording the results. It was then repeated but we removed the catalase (potato) and added Lead Nitrate in its place, we again tested this experiment WebThis is due to the release of oxygen gas as the hydrogen peroxide decomposes. The oxygen gas is what causes the bubbling and foaming, as it becomes trapped in the potato slices. After 10 minutes, remove the potato slices from the solution and place them on a plate or paper towel to dry.
