1. 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.
2. Which gastric enzyme present in infants coagulates milk?
- A. Casein.
- B. Pepsinogen.
- C. Trypsin.
- D. Rennin.
Correct answer: D
Rationale: The correct answer is D, rennin. Rennin is the enzyme in infants responsible for coagulating milk, which aids in the digestion process. Choice A, casein, is a milk protein and not an enzyme. Choices B and C, pepsinogen and trypsin, are digestive enzymes but are not specifically involved in coagulating milk in infants.
3. Carbohydrates are composed of a combination of carbon, hydrogen, and which other element?
- A. oxygen.
- B. nitrogen.
- C. water.
- D. glucose.
Correct answer: A
Rationale: Carbohydrates are composed of carbon, hydrogen, and oxygen. These three elements combine to form the basic structure of carbohydrates. Oxygen is an essential element in carbohydrates, contributing to their chemical composition. Choice B (nitrogen) is incorrect as nitrogen is not a typical component of carbohydrates. Choice C (water) is incorrect as water is not an element but a compound composed of hydrogen and oxygen. Choice D (glucose) is incorrect as glucose is a specific type of sugar, not an element found in the composition of carbohydrates.
4. Which lipoprotein increases the risk of cardiovascular disease?
- A. Low-density lipoprotein (LDL)
- B. High-density lipoprotein (HDL)
- C. Very low-density lipoprotein (VLDL)
- D. Chylomicrons
Correct answer: A
Rationale: The correct answer is A: Low-density lipoprotein (LDL). LDL is often referred to as 'bad cholesterol' because it can lead to plaque buildup in arteries, increasing the risk of cardiovascular disease. High-density lipoprotein (HDL) is considered 'good cholesterol' as it helps remove LDL from the arteries, reducing the risk of cardiovascular issues. Very low-density lipoprotein (VLDL) and chylomicrons are also lipoproteins that transport fats in the bloodstream, but they are not as strongly associated with an increased risk of cardiovascular disease as LDL.
5. What is the chemical structure that forms the base component of an amino acid?
- A. carboxyl group
- B. carbon chain
- C. radicals
- D. amino group
Correct answer: D
Rationale: The correct answer is the amino group. Amino acids consist of an amino group (NH2), a carboxyl group (COOH), a hydrogen atom, and a variable side chain attached to a central carbon atom. The amino group is essential for the formation of proteins. The carboxyl group is not the base component but another important functional group in amino acids. Carbon chain and radicals are not specific chemical structures that form the base component of an amino acid.
