| Digestion | Process of breaking down large insoluble food substances to small soluble food substances |
| Carbohydrates | Nutrient which provide us with energy |
| Glucose | Type of carbohydrate. Single molecule of simple sugar |
| Maltose | Type of carbohydrate. Two units of glucose joined together |
| Starch | Type of carbohydrate. A long chain of glucose molecules joined together |
| Protein | Nutrient which aids in growth and repair of cells and tissues |
| Amino acids | Simplest form of protein |
| Polypeptides | Short chains of protein made up of a few amino acids joined together |
| Fat | Nutrient which provides insulation against cold and impact. Secondary source of energy |
| Glycerol | Simplest form of fat. 3 fatty acids join with 1 glycerol to form 1 molecule of fat |
| Fatty acid | Simplest form of fat. 3 fatty acids join with 1 glycerol to form 1 molecule of fat |
| Enzyme | Biological catalyst (molecules produced by living cells to speed up reactions) |
| Amylase | Type of enzyme. Digests starch to maltose. Found in saliva (mouth) and small intestine. |
| Protease | Type of enzyme. Digests protein to polypeptides, and polypeptides to amino acids. Found in gastric juice (stomach) and small intestine. |
| Maltase | Type of enzyme. Digests maltose to glucose. Found in small intestine. |
| Lipase | Type of enzyme. Digests fat to glycerol and fatty acids. Found in small intestine. |
| Bile | Greenish liquid produced in liver, stored in gall bladder, used in small intestine. Breaks large fat drops into small fat droplets for faster enzyme reaction. |
