The activity of catalase can be measured by finding the rate of oxygen release from hydrogen peroxide potato provides a suitable source of catalase and the ph is varied in this experiment using citric acid-sodium phosphate buffer solutions at ph values of 44, 52, 65 and 75. Enzyme activity, specifically is the rate at which the enzyme catalyses the chemical reaction this is affected by three main factors: 1) temperature, 2) ph and 3) substrate concentration another factor is the enzyme concentration but it is not included in the syllabus. If the catalase concentration double then the rate of hydrogen of catalase to water will also double electronic balancer fine sand thermometer method as you begin the experimentbarnes 1 oxygen release by from hydrogen peroxide mortar permanent marker tape. The increase in the rate of reaction is limited when molecules of the substrate are in short supply and this because there are different number of variables that aids in determining the decomposition of hydrogen peroxide in the presence of the enzyme catalase. Effect of ph on enzyme activity shown on a graph hypothesis the reaction time of the decomposition of hydrogen peroxide (involving catalase) will increase at phs above and below the optimal ph of 7 of the enzyme.

The measurement of the buffer solutions, hydrogen peroxide and cutting of potato discs will have had slight discrepancies in their quantities this will have had a small effect on the results as the enzyme and substrate amounts will have varied and the rate at which products are. As to compare the effect of hydrogen peroxide concentration on catalase in this experiment, the independent variable is the concentration of hydrogen peroxide the dependent variable is the volume of oxygen which is released by hydrogen peroxide showing the rate of the reaction. 2018-10-8  class practical or demonstration hydrogen peroxide (h2o2) is a by-product of respiration and is made in all living cells hydrogen peroxide is harmful and must be removed as soon as it is produced in the cell cells make the enzyme catalase to remove hydrogen peroxide. An investigation into how the concentration of the substrate 'hydrogen peroxide' affects the rate at which it is broken down to oxygen and water by the enzyme catalase hydrogen peroxide is released due to many metabolic reactions in the body, which gives toxicity to the living cells.
