1. Enzymes

2. Definition Enzymes are proteins produced by the living cells,which are capable of catalyzing a chemical reaction in living organisms to yield specific products without getting used up. They never initiates any reaction rather only accelerats the pre-existing reaction . Enzymes are biological catalysta.

3. Catalyst These are the agents which in minutes amount increase the velocity of a reaction without appearing in the final product of a reaction

4. Substrate The compound on which an enzyme acts is called substrate

5. Classification of enzymes Enzymes are classified into six major classes, which are further divided into sub-classes . The main classes are Oxidoreductases Transferase Lyases Isomerases

6. Oxidoreductases They catalyze oxidation – reduction reaction They are subdivided into 5 sub groups De hydrogenase Oxidase Oxygenases Hydrogen peroxidase

7. A- Dehydrogenase These oxidoreductases remove H2 from the substrate If the reaction take place in the presence of O2is called Aerobic dehydrogenase Example
