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.
The effect of temperature on catalase activity. 3 star(s) When enzymes denature the heat starts to destroy their shape and structure. The shape of the enzyme is so important to its working that any change in the shape of the molecules will make them less effective or stop them working completely.
