Match the following vocabulary with their terms. metabolism vitamins minerals lipids carbohydrates proteins enzymes 1.organic compounds that contain carbon, hydrogen and oxygen and are the main source of energy for the body. 2.inorganic substances found in foods needed for growth, regulation and development. 3.organic substances found in foods that aid enzymes. 4.fats, oils, and waxes that are insoluble in water. 5.organic compounds composed of amino acids that form the structure of the body. 6.proteins that drive the chemical reactions that occur in the body. 7.the conversion of the energy found in foods into a usable form of energy for the body.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

the answer is b.) hydrogen bonds between bases.
