1. Which component of fat can be used to make glucose through gluconeogenesis?

• A. Glycogen
• B. Fatty acids
• C. Glycerol
• D. Monoglyceride

Correct answer: C

Rationale: The correct answer is 'Glycerol.' Glycerol, a component of fat, can be converted into glucose through gluconeogenesis. Glycogen (Choice A) is a polysaccharide stored in animals, not a component of fat. Fatty acids (Choice B) are used primarily for energy production through beta-oxidation, not for gluconeogenesis. Monoglyceride (Choice D) is a molecule formed during fat digestion, but it is not the component of fat that can be used to make glucose.

2. Where does the major portion of the chemical digestion of lipids occur?

• A. Mouth.
• B. Stomach.
• C. Small intestine.
• D. Large intestine.

Correct answer: C

Rationale: The correct answer is C: Small intestine. The majority of lipid digestion occurs in the small intestine, where bile and pancreatic lipase are active. Lipids are broken down into fatty acids and glycerol in the small intestine. Choices A, B, and D are incorrect because the mouth and stomach play minor roles in lipid digestion, and the large intestine is mainly responsible for absorbing water and electrolytes from the indigestible food residues.

3. In the most recent edition of Choose Your Foods: Exchange List for Diabetes, the three groups into which foods are arranged are:

• A. fruits and vegetables, breads, and meats.
• B. fats, starches and sugars, and meat and milk.
• C. fruits and vegetables, meat and milk, and starches.
• D. carbohydrates, meat and meat substitutes, and fats.

Correct answer: D

Rationale: The correct answer is D: carbohydrates, meat and meat substitutes, and fats. The most recent edition of Choose Your Foods: Exchange List for Diabetes categorizes foods into these three groups for easier meal planning. Choice A is incorrect because it does not include carbohydrates and groups bread with fruits and vegetables. Choice B is incorrect because it separates carbohydrates into starches and sugars, which are usually counted together in diabetes meal planning. Choice C is incorrect as it does not specifically categorize foods into carbohydrates, meat, and fats as per the latest edition.

4. In which individual does negative nitrogen balance occur?

• A. Adult who engages in a weight-training program.
• B. Woman who is pregnant or lactating.
• C. Child who is growing.
• D. Older adult with anorexia.

Correct answer: D

Rationale: Negative nitrogen balance occurs when the body loses more nitrogen than it gains. This imbalance is often seen in conditions like anorexia in older adults, where insufficient protein intake leads to muscle breakdown and negative nitrogen balance. Choices A, B, and C do not typically lead to negative nitrogen balance as seen in anorexia in older adults.

5. Which chain length of fatty acids is most water-soluble and easily absorbed into the bloodstream?

• A. Very long.
• B. Long.
• C. Medium.
• D. Short.

Correct answer: D

Rationale: Short-chain fatty acids are the most water-soluble and are more easily absorbed into the bloodstream. Very long, long, and medium-chain fatty acids are less water-soluble and are absorbed at a slower rate compared to short-chain fatty acids. Therefore, the correct answer is D.
