13. Which of the following is a benefit attributed to fructooligosaccharides that are found
naturally in some fruits and vegetable and are commercially produced as reduced-calorie
sweeteners?
A. Increased triglyceride levels
B. Relief of constipation
C. Decreased glycogen storage
D. Increased amino acid production
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. Which enzyme begins the process of carbohydrate digestion?
A. Pancreatic amylase
B. Insulin
C. Salivary amylase
D. Glucagon
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. What substance is released by the pancreas into the duodenum to create a more alkaline
environment to allow the digestive enzymes to perform their assigned functions in
carbohydrate digestion?
A. Insulin
B. Glucagon
C. Pancreatic amylase
D. Bicarbonate
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. 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

18. All types of carbohydrates provide 4 calories per gram.

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. Research indicates that consuming foods with a lower glycemic load may offer significant
health benefits, including weight control and decreased risk of diabetes and heart disease.

ANS: T

, ______________________________________________________________________________________________
Test Bank - Sports Nutrition for Health Professionals, 2nd Edition (Muth, 2020)

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. The average American consumes and exceeds the daily recommendations for fiber intake.

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

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.
10. Bolus passes through the esophagus.

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.
