Introduction: Enzymes are large proteins and catalysts and increase the speed of a chemical reaction without undergoing any permanent chemical change. They are neither used up in the reaction nor do they appear as reaction products. 2 Enzymes, such as Catalase, are globular protein molecules which are found in living cells. 3 In their globular structure, one or more polypeptide chains twist and fold, bringing together a small number of amino acids to form the active site, or the location on the enzyme where the substrate binds and the reaction takes place.
