- PLEASE ANSWER C AND D IN QUESTIONS ASKED AT THE END BASED ON GIVEN INFORMATION 1. The Effect of Various Factors on the Rate of an Enzyme Reaction. These experiments will use the enzyme catalase, which is found in potatoes. Catalase acts on the substrate, H2O2 (hydrogen peroxide), to produce H2O and O2. The O2 is released as bubbles. Therefore, the more bubbles you see, the greater the reaction.
