Biomolecules are organic molecule present in living organisms.They are of four types carbohydrate, protein, lipid, nucleic acid. Carbohydrates are polyhydroxy aldehydes and ketones which are classified in three types; Monosaccharides, disaccharides and polysaccharides.
Enzymes are biological catalysts which increase the rate of reaction without even participated in the reaction. Enzymes are classified into six classes.
Each and every enzymes are specific to catalyze a particular reaction. Enzymes are also inhibited by different kinds of inhibitors. All enzymes performs variety of functions.
