Enzyme Action: Testing Catalase Activity Introduction: Enzymes are proteins that serve as catalysts and accelerate chemical reactions in living organisms. Enzymes accomplish this by lowering the energy of activation of the organism it is acting upon, however enzymes will only lower the energy of activation for specific organisms, reducing chaotic chemical reactions. The reaction is carried out in it’s entirety in the active site of the enzyme. The substrate (organism acted upon), binds itself …

…concentration. A small amount of human error was included within this experiment, for example shaking (inadvertently) the test tube while gas pressure was being measured. However these errors weren’t significant enough to have influential effects on the overall results of these experiments. In conclusion, this experiment leads one to assume increasing enzyme concentration and pH continually, will increase reaction activity, and increasing the temperature will increase the reaction rate up until a certain point.
