BIOMOLECULES AND ENZYMES

Detailed explanation-1: -First, they increase the rate of chemical reactions without themselves being consumed or permanently altered by the reaction. Second, they increase reaction rates without altering the chemical equilibrium between reactants and products.

Detailed explanation-2: -Examples are lactase, alcohol dehydrogenase and DNA polymerase.

Detailed explanation-3: -Enzymes and catalysts both affect the rate of a reaction. In fact, all known enzymes are catalysts, but not all catalysts are enzymes. The difference between catalysts and enzymes is that enzymes are largely organic in nature and are bio-catalysts, while non-enzymatic catalysts can be inorganic compounds.
