Enzymes classification Enzymes is protein, Enzyme  Increase the rate of reaction Enzymes can be classified into six major classes based on the nature and type of reaction catalyzed as given. Oxidoreductase Transferase Hydrolase Layses Isomerase Liagases. Oxidoreductase enzyme catalysed oxidation or reduction by transfer of hydrogen or electron examples Succinic dehydrogenase. Transferases. Enzyme are involved in transfer of functional group with donor and acceptor. Example are glutamic pyruvic transminase. Hydrolases Enzymes can be  transfer of  water group. Reaction involved hydrolytic cleavage of c-o, c- n ,o- p , and c-s bonds. Example peptidases. Proteolytic enzymes are special class of hydrolases. Layses These enzymes remove the group of  water ammonia  or  carbon dioxide from this substrate to cleave double bond. Example furmarase. Isomerases these are a very heterogeneous group of enzymes that catalyze isomerasation. These include cis-trans ,keto-eno...

Enzymes Enzymes are biocatalyst. Catalyst means increase the velocity or rate of chemical reaction without itself undergoing any change in overall process. Enzymes is protein that is synthesized in a living cell. Enzymes absence in chemical reaction then  it is slow process of reaction. Enzymes are sensitive to temperature. Also sensitive to PH. All protein is not enzymes. All enzymes are protein. Holoenzyme Completely catalytic active in Enzyme. Holoenzyme is apoenzyme + cofactor. Holoenzyme is active Apoenzyme is inactive Cofactor is inactive. Cofactor Non proteins component of the enzyme. Cofactor can be classified into three groups Coenzyme prosthetic group and  metals ions.
