LIFE SCIENCE

Detailed explanation-1: -Enzymes allow reactions to occur at the rate necessary for life. In animals, an important function of enzymes is to help digest food. Digestive enzymes speedup reactions that break down large molecules of carbohydrates, proteins, and fats into smaller molecule s the body can use.

Detailed explanation-2: -Enzymes are proteins that allow organisms to accelerate life processes. Enzymes are essential to life because they help chemical reactions occur quickly and at relatively low temperatures. For example, enzymes transform raw chemical materials and convert them into energy and wastes.

Detailed explanation-3: -Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes. Our bodies naturally produce enzymes.

Detailed explanation-4: -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.
