1. Which of the following saturated fats does not contain cholesterol?

• A. Butter
• B. Coconut oil
• C. Eggs
• D. Fish

Correct answer: B

Rationale: The correct answer is B, Coconut oil. Coconut oil is a saturated fat derived from plants and does not contain cholesterol, unlike the other options. Butter (choice A) is an animal-derived saturated fat that contains cholesterol. Eggs (choice C) and fish (choice D) also contain cholesterol, making them incorrect choices. Therefore, coconut oil is the only option that is a saturated fat and does not contain cholesterol.

2. An example of government nutrition policy is:

• A. MyPlate Food Guidance System.
• B. Dietary Guidelines for Americans 2010.
• C. Healthy People 2020.
• D. Dietary Reference Intakes (DRIs).

Correct answer: C

Rationale: The correct answer is C: Healthy People 2020. Healthy People 2020 is a government initiative that sets goals for improving the health of Americans, including specific nutritional objectives. Choices A, B, and D are not examples of government nutrition policies. MyPlate Food Guidance System is a visual tool to help individuals make healthy food choices, Dietary Guidelines for Americans 2010 provide evidence-based advice for Americans two years and older, and Dietary Reference Intakes (DRIs) are a set of nutrient reference values.

3. Which hormone is responsible for stimulating the gallbladder to contract and release bile?

• A. gastric lipase
• B. cholecystokinin
• C. vitamin D
• D. enterokinin

Correct answer: B

Rationale: Cholecystokinin (CCK) is the correct answer. It is the hormone responsible for stimulating the gallbladder to contract and release bile to aid in fat digestion. Gastric lipase (Choice A) is an enzyme that breaks down fats in the stomach, not a hormone involved in gallbladder function. Vitamin D (Choice C) is important for calcium absorption and bone health, but it is not directly related to gallbladder function. Enterokinin (Choice D) is a peptide hormone that affects smooth muscle contractions in the gastrointestinal tract, but it is not specifically responsible for stimulating the gallbladder to release bile.

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. 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.
