What are enzymes? Give examples?PLEASE GIVE ANSWER..............

 

Enzymes are the important group of globular proteins which acts as biological catalysts inLiving systems. Enzymes increase the rate of biochemical reactions by providing alternativepath of lower activation energy.

 

E.g.:Activation energy of acid hydrolysis of sucrose is16.22 .KJ mole−. While the activationenergy is only12.15 .KJ mole− when hydrolysed by enzyme, sucrase. Enzymes are highly specific in their action. Each enzyme can catalyse only a specific type of reaction enzymes which catalyse the oxidation of one substrate with reduction of another substrate are named as ‘oxidoreductase’ enzymes. Enzymes are needed only in small quantities for the progress of a reaction.
