    INTRODUCTION Enzymes are a protein serving as a catalyst, a chemical agent that changes the rate of the reaction without being consumed by the reaction. Enzymes are proteins made up of long chains of amino acids. These form complex shapes. The enzymes are individuals, like the different players on a ball team, they have different specific structures and jobs. As one ball player may be very tall and one short, the specific different shape of the active site on an enzyme is unique and prepares it...
