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.
Catalase (like many enzymes) has a specific function. This is because of the unique shape of the catalase molecule. Its shape allows the enzyme to bond with a specific substrate (such as hydrogen peroxide). A substrate is the compound with which an enzyme bonds. Think of it as a lock and key. In our example, catalase represents the lock, and the hydrogen peroxide represents the key.
