Since catalase can be very useful both for commercial and industrial purposes, [2], it is natural that there is an interest to characterize the activity of this enzyme. Catalase activity is a function of aerobic process. A catalyst is defined as a substance that increases the rate of alchemical reaction without itself undergoing any permanent chemical change. Catalase is an enzyme, which is produced by microorganisms that live in oxygenated environments to neutralize toxic forms of oxygen metabolites; H 2 O 2. How We Collected Our Data: We took 5 clean test tubes, labeled them 1-5, and put 2 ml of hydrogen peroxide in each tube. Some types of cells contain more catalase than other types of cells. Hydrogen peroxide at high concentrations is a toxic agent, while at low concentrations it appears to modulate some physiological processes such as signaling in cell proliferation, apoptosis, carbohydrate metabolism, and platelet activation. 0 20 of pH 7 2. The materials are appropriate for the procedure. As catalase speeds up the production of oxygen gas; we are able to measure the rate of enzyme activity, which can be measured as the height of the column of oxygen gas bubbles produced in a test tube. View Enzyme Catalysis Lab Report. Hydrogen peroxide comes from the breakdown of alcohol. Effect of Temperature on Enzyme Catalase Activity in potato Aim: To investigate the effect of temperature (10, 37, 60). Immediate vigorous oxygen bubbles indicates catalase-positive bacteria. Having the molecules cold, allows them to slow the reaction down. WHEN catalase is added to hydrogen peroxide, there is an initial rapid evolution of oxygen which lasts for about two minutes, depending on the peroxide concentration. Take a loop full of colonies from a plate of each bacterium and place inoculum separately on a glass microscope slide.

However, they also show that the temperature at which the reaction occurred also greatly impacted the rate of reaction, to the point where the final amount of chilled oxygen was just %20. Once the catalase solution is prepared, it should be refrigerated. Catalase accelerates the breakdown of hydrogen peroxide (H 2 O 2) into water and oxygen. One function of catalase within cells is to prevent the accumulation of toxic levels of hydrogen peroxide (formed as a by-product of metabolic processes. This experiment should make it possible to determine the optimum temperature for catalase activity. In conditions with high hydrogen peroxide concentration, catalase works to convert two molecules of H 2 O 2. The effects of catalase, like those of all enzymes, are influenced by the surrounding temperature. txt) or read online for free. Most tissues, however, contain the enzyme catalase, which catalyzes the breakdown of peroxide to water and oxygen as follows:. As the catalase breaks down the hydrogen peroxi de into water and oxygen gas, the bubbles of oxygen collect underneath the filter and make it rise to the surface of the hydrogen peroxide.
