= CARBOHYDRATES
2. Inorganic substances found in foods needed for growth, regulation and development.
= MINERALS
3. Organic substances found in foods that aid enzymes. = VITAMINS
4. Fats, oils, and waxes that are insoluble in water. = LIPIDS
5. Organic compounds composed of amino acids that form the structure of the body.
= PROTEINS
6. Proteins that help drive the chemical reactions that occur in the body.
= ENZYMES
7. The conversion of the energy found in foods into a usable form of energy for the body.
= METABOLISM
