1. Individuals with optimal nutritional status differ from those with marginal nutritional status in their:
- A. nutrient reserves.
- B. clinical signs.
- C. body weight.
- D. risk of mental illness.
Correct answer: A
Rationale: Individuals with optimal nutritional status differ from those with marginal nutritional status in their nutrient reserves. Optimal nutritional status implies having adequate nutrient reserves, which is lacking in marginal status. Clinical signs (choice B) may or may not be present in both groups and are not the differentiating factor between optimal and marginal statuses. Body weight (choice C) can vary for reasons other than nutritional status. The risk of mental illness (choice D) is not directly related to the comparison between optimal and marginal nutritional status.
2. Cholecystokinin (CCK) is produced in the:
- A. duodenum.
- B. stomach.
- C. pancreas.
- D. liver.
Correct answer: A
Rationale: Cholecystokinin (CCK) is produced in the duodenum, not the stomach, pancreas, or liver. It is released in response to the presence of food in the duodenum, where it plays a crucial role in regulating digestive processes by stimulating the release of bile from the gallbladder and enzymes from the pancreas. Therefore, the correct answer is the duodenum (Choice A). Choices B, C, and D are incorrect because CCK is not produced in the stomach, pancreas, or liver.
3. 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.
4. Which hormone prevents excessive gastric activity?
- A. Gastrin
- B. Enterogastrone
- C. Secretin
- D. Cholecystokinin
Correct answer: B
Rationale: The correct answer is Enterogastrone. Enterogastrone is a hormone that inhibits excessive gastric activity by slowing down stomach contractions and emptying. Gastrin (choice A) stimulates gastric acid secretion, secretin (choice C) regulates pH levels in the duodenum, and cholecystokinin (choice D) stimulates the release of digestive enzymes and bile.
5. People with phenylketonuria should avoid foods made with which nonnutritive sweetener?
- A. acesulfame-K
- B. aspartame
- C. saccharin
- D. sucralose
Correct answer: B
Rationale: People with phenylketonuria should avoid aspartame because it contains phenylalanine, which they cannot metabolize. Acesulfame-K, saccharin, and sucralose do not contain phenylalanine and are safe for individuals with phenylketonuria. Therefore, the correct answer is B. Acesulfame-K, saccharin, and sucralose are incorrect choices because they do not pose a risk for individuals with phenylketonuria due to the absence of phenylalanine in their composition.
