Answer Section
MULTIPLE CHOICE
1. ANS: B
Rationale: Lactose is a disaccharide, and fructose and galactose must be converted to glucose for the cells to
use for energy.
PTS: 1 DIF: Easy OBJ: 1-1
KEY: monosaccharide | glucose | energy sources
2. ANS: A
Rationale: The body stores carbohydrates as glycogen in the liver and muscles.
PTS: 1 DIF: Easy OBJ: 1-1 | 1-4 KEY: glycogen | carbohydrate storage
3. ANS: A
Rationale: The stevia plant produces a noncaloric, all-natural sweetener.
PTS: 1 DIF: Easy OBJ: 1-1 KEY: stevia | noncaloric sweeteners
4. ANS: D
Rationale: Oligosaccharides are chains of three to ten monosaccharides. Amylose and amylopectin are
examples of polysaccharide starches, and galactose is a monosaccharide.
PTS: 1 DIF: Easy OBJ: 1-2 KEY: oligosaccharide
5. ANS: B
Rationale: Amylose is resistant to digestion. Cellulose is a basically indigestible fiber, and glycogen is not a
form of starch.
PTS: 1 DIF: Easy OBJ: 1-2 KEY: starch | carbohydrate structure
6. ANS: C
Rationale: The enzyme lactase is responsible for breaking lactose into its component parts. The inability to
break down lactose results in painful gastrointestinal symptoms like abdominal cramps, bloating, diarrhea,
and flatulence.
PTS: 1 DIF: Moderate OBJ: 1-4
KEY: lactose intolerance | carbohydrate digestion
7. ANS: C
Rationale: The body can store approximately 240 g of glycogen (90 g in the liver and 150 g in the muscles).
Any additional glucose not needed for normal body activity is converted to fat for storage.
PTS: 1 DIF: Moderate OBJ: 1-4 KEY: glycogen | carbohydrate storage
8. ANS: A
Rationale: Insulin and glucagon, the hormones responsible for regulating blood sugar, are produced in the
pancreas.
Copyright © 2020 F. A. Davis Company
, PTS: 1 DIF: Moderate OBJ: 1-5 KEY: blood sugar
9. ANS: C
Rationale: AMDR is 45% to 65% of calories from carbohydrates. For an individual consuming a 3,000-
calorie diet, that is 1,350 to 1,950 calories. Carbohydrates carry 4 cal/g.
PTS: 1 DIF: Difficult OBJ: 1-5
KEY: recommended intake | AMDR | acceptable macronutrient distribution range
10. ANS: C
Rationale: GL = (GI g CHO)/100; GL = (40 15 g CHO)/100; GL = 6
PTS: 1 DIF: Difficult OBJ: 1-6 KEY: glycemic load
11. ANS: D
Rationale: Gluconeogenesis occurs when there is limited glucose or glycogen available as an energy source.
PTS: 1 DIF: Moderate OBJ: 1-8 KEY: gluconeogenesis
12. ANS: A
Rationale: Glycosidic bonds connect monosaccharides together to form the other types of carbohydrate
chains.
PTS: 1 DIF: Easy OBJ: 1-1 KEY: glycosidic bond
13. ANS: B
Rationale: Fructooligosaccharide use has been associated with constipation relief, improved triglyceride
levels, and decreased production of foul-smelling digestive by-products.
PTS: 1 DIF: Moderate OBJ: 1-1 KEY: fructooligosaccharides
14. ANS: C
Rationale: Digestion of carbohydrates begins in the mouth when salivary amylase breaks large
polysaccharides into oligosaccharides and disaccharides.
PTS: 1 DIF: Easy OBJ: 1-4
KEY: salivary amylase | carbohydrate digestion
15. ANS: D
Rationale: Bicarbonate results in a more alkaline environment, so digestive enzymes can survive the acidity of
the materials moving into the small intestine from the stomach.
PTS: 1 DIF: Moderate OBJ: 1-4 KEY: bicarbonate | carbohydrate digestion
MULTIPLE RESPONSE
16. 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. ANS: A, B, C, D
Copyright © 2020 F. A. Davis Company
, 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
18. ANS: F
Rationale: Most carbohydrates provide 4 calories per gram; however, dietary fiber contributes approximately
1.5 to 2.5 calories per gram.
PTS: 1 DIF: Easy OBJ: 1-1 KEY: calorie
19. ANS: T
Rationale: Significant health benefits are associated with low-glycemic-load foods due to their nutrient
density and the stability they provide to blood sugar and insulin levels.
PTS: 1 DIF: Easy OBJ: 1-6 KEY: glycemic load
20. ANS: F
Rationale: Americans consume far less than the recommended fiber intake of 14 g per 1000 calories, or 25 to
35 g per day.
PTS: 1 DIF: Easy OBJ: 1-7 KEY: fiber
COMPLETION
21. ANS: 3, 10, 4, 1, 2, 5, 7, 9, 6, 8
PTS: 1 DIF: Difficult OBJ: 1-4 KEY: carbohydrate digestion
SHORT ANSWER
22. 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.
PTS: 1 DIF: Difficult OBJ: 1-5 KEY: insulin | glucagon
23. ANS:
Glycemic load accounts for portion size while glycemic index solely measures the impact of a food on blood
sugar levels compared with a reference amount of 50 g of carbohydrates. Foods can have a high glycemic
index but a small typical portion size and therefore a low glycemic load. In addition, very few foods are
composed solely of carbohydrates. The fat, protein, and fiber in a food also lowers the glycemic load.
