The principle of conservation of energy. Energy can be transferred and transformed, but it cannot be created or destroyed.EX. Food (chemical energy)- movement + heat

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. But enzymes are also in manufactured products and food.
