Enzymes are proteins made by cells in our bodies. They are specialized proteins that do work, such as synthesizing chemicals and compounds, rearranging molecules, adding elements to compounds, and breaking down compounds. There are many types of enzymes, and each type does a specific function. For an enzyme to work, it must have access to its substrate, the material upon which an enzyme exerts an action. If no substrate is available to the enzyme, the enzyme performs no function. For example, an enzyme called catalase is present in our blood. Catalase converts hydrogen peroxide to water and oxygen, which is why peroxide bubbles when it is placed on a wound. Since peroxide is not usually in our blood, catalase circulates within the blood, doing nothing until peroxide is introduced into the system. A substrate works as an "on-off" switch for its particular enzyme. Catalase will only be activated in the presence of peroxide and nothing else.


Enzymes work as catalysts of biochemical reactions. A catalyst increases or accelerates the rate of a chemical reaction. The thousands of chemical reactions that occur in our body every second could not happen without enzymes to speed up these reactions. For example, a protein can be broken down into amino acids in the lab without the use of an enzyme, but to do so requires extreme temperatures, high pressure, and very strong acids; conditions not compatible with life. Even with these conditions, it requires hours to complete the reaction in the lab. With enzymes, in this case a mixture of proteases, the reaction can be completed within minutes in water at normal temperatures.
