1. Which types of acids form the basic building blocks of protein?

• A. fatty
• B. amino
• C. nucleic
• D. omega fatty

Correct answer: B

Rationale: The correct answer is 'B: amino.' Amino acids are the fundamental units that make up proteins. They are essential for various bodily functions, including building and repairing tissues. Choice A, 'fatty acids,' are not the basic building blocks of proteins but rather a type of lipid. Choice C, 'nucleic acids,' are the building blocks of nucleic acids like DNA and RNA, not proteins. Choice D, 'omega fatty acids,' are a specific type of fatty acid known for their health benefits but are not directly related to the building blocks of proteins.

2. The Acceptable Macronutrient Distribution Range for fat recommends that the percentage of total kcalories from fat should fall between:

• A. 10% and 20%.
• B. 20% and 25%.
• C. 20% and 35%.
• D. 30% and 45%.

Correct answer: C

Rationale: The Acceptable Macronutrient Distribution Range (AMDR) for fat suggests that 20% to 35% of total kcalories should come from fat. This range is recommended to maintain good health. Choices A, B, and D are incorrect because they do not fall within the specified range. A lower percentage (10-20%) may not provide enough essential fatty acids, while a higher percentage (30-45%) may increase the risk of health issues associated with excessive fat consumption.

3. Exchange Lists for Meal Planning was devised by the American Dietetic Association in collaboration with which organization?

• A. the American Cancer Society
• B. the American Diabetes Association
• C. the American Heart Association
• D. the Culinary Institute of America

Correct answer: B

Rationale: The correct answer is B: the American Diabetes Association. The American Dietetic Association collaborated with the American Diabetes Association to devise the Exchange Lists for Meal Planning. This collaboration aimed to assist individuals, especially those with diabetes, in planning balanced meals. Choices A, C, and D are incorrect as they were not involved in the development of the Exchange Lists.

4. 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.

5. What are the major sources of energy for the body?

• A. Proteins and fats.
• B. Carbohydrates and fats.
• C. Proteins and carbohydrates.
• D. Vitamins and minerals.

Correct answer: B

Rationale: The correct answer is B: Carbohydrates and fats. Carbohydrates are the body's primary and most efficient source of energy, providing fuel for daily activities. Fats are also a significant energy source, especially during times of prolonged or intense exercise. Proteins are primarily used for building and repairing tissues, not as a major energy source. Vitamins and minerals are essential for various bodily functions but do not serve as direct sources of energy.
