An enzyme is a catalyst, which is a chemical agent that changes the rate of a reaction without being consumed by the reaction. The reactant that enzymes act on is called its substrate. While the enzyme is bound to the substrate, the catalytic action converts the substrate to the product. Because of its shape, each enzyme catalyzes a specific reaction, which is the molecular recognition. Only a certain region of the enzyme molecule actually binds …

…induced-fit binding of a substrate molecule to one polypeptide subunit can change the conformation such that the active sites of all subunits are more active. An experiment that you could do would be with the substrate and the enzyme. You could leave one test-tube in room temperature, one test-tube over heat and one test-tube over ice. If temperature influences enzyme activity, then the rate of reaction will increase or decrease with the changes in temperature.
