What is an enzyme? Two ways of increasing the rate of a chemical reactions: o Increasing the temperature (adding energy in the form of heat). This one is not so  realistic because biological processes only work at a certain optimal temperature. o Adding a catalyst accelerates the reaction. It participates in the reaction yet  emerges at the end in its original form. Most enzymes are proteins, but a few are made of RNA called ribozymes. Cymotrypsin  is a digestive enzyme synthesized in the pancreas and secreted into the  small intestine, where it helps break down dietary protein. It catalyzes the hydrolysis of  peptide bonds. Most biological enzymes are highly specific. This is enabled by the functional groups  present in the active site of an enzyme. Multiple enzymes catalyzing the same reaction are called isozymes. Enzyme Classification Class of Enzyme Type of reaction catalyzed 1. Oxidoreductases Oxidation-reduction reactions 2. Transferases Transfer of functional group 3. Hydrolases Hydrolysis reactions 4. Lyases Group elimination to form double bonds 5. Isomerases
