Enzymes are protein molecules that speed up a chemical reaction by lowering the activation. energy. In this experiment, the action of catalase was tested on different types of tissue extracts.n enzyme called catalase breaks down hydrogen peroxide into water and oxygen. In experiment number 3, we are comparing the action of catalase in different tissues by testing this hypothesis: The breakdown of hydrogen peroxide occurs at the same rate in all cells.
[113] Action The reaction of catalase in the decomposition of living tissue:2 H 2 O 2 â 2 H 2 O + O 2 The presence of catalase in a microbial or tissue sample can be tested by adding a volume of hydrogen peroxide andobserving the reaction. The formation of bubbles, oxygen, indicates a positive result.
