MULTIPLE RESPONSE
16. Which of the following statements describes what happens after digested sugars are
delivered to the liver through the portal system? Select all that apply.
A. Fructose and galactose are converted to glucose.
B. Glucose is converted to glycogen and stored in the pancreas for later use.
C. Glucose enters the bloodstream based on body needs.
D. Glucose is converted to fat based on body needs.
ANS: A, C, D
Rationale: Sugars may be converted to glycogen, but glycogen is stored in the muscles and
liver, not the pancreas.
PTS: 1 DIF: Difficult OBJ: 1-4
KEY: portal system | glycogen | carbohydrate absorption
17. Which of the following are considered health benefits associated with high-viscosity fiber
consumption? Select all that apply.
A. Increased feeling of fullness
B. Decreased fat absorption
C. Decreased cholesterol levels
D. Decreased insulin resistance
ANS: A, B, C, D
Rationale: High-viscosity or soluble fiber typically slows gastric emptying, which
contributes to feelings of fullness and better regulation of blood sugar levels. In addition, it
interferes with fat and cholesterol absorption and recirculation. This fiber is also linked in
improving cells’ sensitivity to insulin, therefore decreasing insulin resistance and type 2
diabetes risk.
PTS: 1 DIF: Difficult OBJ: 1-7
KEY: high-viscosity fiber | soluble fiber
TRUE/FALSE

PTS: 1 DIF: Easy OBJ: 1-7 KEY: fiber
ORDERED RESPONSE
21. Place the steps of carbohydrate digestion in order. (1 to 10)
1. Enzyme action is inhibited due to acidic environment, and bolus is converted to chyme.
2. Chyme passes into the duodenum, and pancreatic enzymes help to break glycosidic
bonds.
3. Salivary amylase begins to break polysaccharides into oligosaccharides and
disaccharides.
4. Bolus moves into the stomach.
5. Brush border enzymes break carbohydrates into monosaccharides, and absorption occurs
into the microvilli.
6. Undigested carbohydrates move into the large intestine.
7. Chyme passes into the jejunum and ileum.
8. Some fiber is partially digested by bacteria through fermentation, and the remaining fiber
is excreted.
9. Monosaccharides absorbed into the bloodstream pass through portal circulation for
distribution or storage.

ANS:
3, 10, 4, 1, 2, 5, 7, 9, 6, 8
PTS: 1 DIF: Difficult OBJ: 1-4
KEY: carbohydrate digestion
SHORT ANSWER
22. Describe the manner in which insulin and glucagon regulate blood sugar levels.
ANS:
When blood sugar levels begin to rise, insulin aids in the uptake of glucose and conversion
of carbohydrates into fat for long-term storage. Glucagon is released when blood sugar
levels decrease; it increases blood sugar levels by regulating the breakdown of glycogen into
glucose and the conversion of fat into fuel to maintain blood glucose levels while
conserving glycogen.
