At least. two different enzymes are known to catalyze this reaction: catalase, found in animals and. protists, and peroxidase, found in plants. A great deal can be learned about enzymes by studying. the rates of enzyme-catalyzed reactions. In this experiment, you will measure the rate of enzyme.

Investigation of How the Concentration of Catalase Enzyme Affects the Rate of Reaction. Aim: To find out how the concentration of Catalase Enzyme will affect the. enzyme activity and the rate of reaction towards Hydrogen Peroxide. (H. O ) Prediction: I predict that with the higher concentration of enzyme, the likelihood. of it breaking down molecules will be greater because there will be.

This decrease of activity is paralleled by a decrease in the steady state concentration of the primary catalase-hydrogen peroxide complex in alkaline solutions. Chance, Britton. Effect of PH upon the Reaction Kinetics of the Enzyme-substrate Compounds of Catalase.. The Journal of Biological Chemistry 194.2 (1952): 471-81. The data show that mag-poly(EGDMA–MAH)–Fe+3-catalase preparation has the same optimum as the free enzyme… It was between 6.5 and 7.0.

Testing Catalase Activity. Many organisms can decompose hydrogen peroxide (H. 2O. 2) enzymatically. Enzymes are globular. proteins, responsible for most of the chemical activities of living organisms. They act as. catalysts, substances that speed up chemical reactions without being destroyed or altered during. the process.

With that in mind, we decided to test the effect of the pH of the environment on the rate of which catalase (the enzyme we chose) breaks down Hydrogen Peroxide. What this truly measures is the effectiveness of the enzyme under different environments.

Cells make the enzyme catalase to remove hydrogen peroxide. This investigation looks at the rate of oxygen production by the catalase in pureed potato as the concentration of hydrogen peroxide varies. The oxygen produced in 30 seconds is collected over water. Then the rate of reaction is calculated.

In doing so, they lower the amount of activation energy needed and thus speed up the reaction. Not only do enzymes economize energy usage, but also provide a variety of other functions. Cells uses an enzyme (catalase) to rid itself of a poisonous substance (hydrogen peroxide).

Rate of enzyme activity = distance (depth of hydrogen peroxide in mm)/time (in sec). Catalase catalyzes the decomposition of hydrogen peroxide into water and oxygen. One molecule of catalase can break 40 million molecules of hydrogen peroxide each second.

The rate at which this occurs depends on the amount of catalase that is available. In this lab we are going to measure the time it takes for a disc of filter paper, soaked with different concentrations of enzyme, to make its way to the top of a plastic vial filled with peroxide.
