Resource summary

Question Answer
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.
