1. What is the basis of MyPlate food guidance?

• A. Percentage of calories from each macronutrient.
• B. Exchange Lists for Meal Planning.
• C. Appropriate amounts of food from each food group.
• D. Amounts of macronutrients and micronutrients.

Correct answer: C

Rationale: The correct answer is C: 'Appropriate amounts of food from each food group.' MyPlate food guidance focuses on portion sizes from different food groups to promote a balanced diet. Choices A, B, and D are incorrect because MyPlate emphasizes the consumption of a variety of foods from different food groups rather than focusing solely on macronutrient percentages, exchange lists, or specific nutrient amounts.

2. What is a major function of glucose?

• A. Produce energy.
• B. Transport oxygen to cells.
• C. Convert fat to glycogen.
• D. Maintain body weight.

Correct answer: A

Rationale: Glucose serves as a primary source of energy for the body, especially for the brain and muscles. Choice B is incorrect because glucose itself is not responsible for transporting oxygen to cells. Choice C is incorrect as glucose is converted to glycogen, not the other way around. Choice D is incorrect as glucose itself does not play a direct role in maintaining body weight.

3. 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.

4. What group makes each amino acid unique?

• A. Radical group
• B. Amino group
• C. Carboxyl group
• D. Peptide bond

Correct answer: A

Rationale: The correct answer is the radical group (R-group) because it is the unique side chain that differentiates each amino acid. The amino group (choice B) and carboxyl group (choice C) are functional groups common to all amino acids but do not make them unique. The peptide bond (choice D) is the bond formed between amino acids in a protein chain, not the group that makes each amino acid unique.

5. What is the process by which proteins are synthesized from the available amino acids?

• A. Gluconeogenesis.
• B. Deamination.
• C. Protein synthesis.
• D. Transamination.

Correct answer: C

Rationale: The correct answer is C: Protein synthesis. This process involves the formation of proteins from amino acids to support various body functions. Gluconeogenesis (choice A) is the synthesis of glucose from non-carbohydrate sources, not protein synthesis. Deamination (choice B) is the removal of an amino group from an amino acid, not the synthesis of proteins. Transamination (choice D) is the transfer of an amino group from one molecule to another, not the direct synthesis of proteins.
