Fructose d. Sucrose e. A, B, & C What can be said about fructose? a. It is metabolized mainly in the liver. b. It can be associated with elevated triglycerides c. t is a disaccharide. d. It has 9 kcal/g. e. A & B are correct.

Explanation / Answer

20. (a) Glucagon increases the blood glucose levels.

21. (e) People with PKU cannot metabolize phenylalanine and food with aspartame have a warning label to alert these patients. A genetic defect in the phenylalanine hydroxylase enzyme is the basis for classical PKU.

22. (e) All of the above are true.

23. (a) Yes it is wise as Catabolism is the set of metabolic pathways that breaks down molecules into smaller units that are either oxidized to release energy, or used in other anabolic reactions.

24. (e) Glucose, Galactose and Fructose are monosaccharides.

25. (e) Fructose has the ability to significantly raise triglyceride levels, which may increase the risk of heart disease. It is metabolised mainly in the liver.
