Catalase Activity in Reaction with the Substrate Hydrogen Peroxide Abstract We performed these experiments to observe the effects of enzymes on the rate of reactions. We tested and compared the activity of the enzyme catalase on the substrate H2O2 in various states and percentages‚ and observed the absorption values of the enzyme-substrate relationship at different concentrations. Our results show that the more substrate available‚ the quicker the reaction will happen except in one test‚ which might
