1. What is the process of converting glycogen to glucose called?

• A. Glucogenesis.
• B. Glycogenolysis.
• C. Glyconeogenesis.
• D. Gluconeogenesis.

Correct answer: B

Rationale: The correct answer is B: Glycogenolysis. Glycogenolysis is the process of breaking down glycogen into glucose. Choices A, C, and D are incorrect. Glucogenesis (choice A) is not a term used in biochemistry. Glyconeogenesis (choice C) refers to the synthesis of new glucose molecules from non-carbohydrate sources, not the breakdown of glycogen. Gluconeogenesis (choice D) is the process of producing glucose from non-carbohydrate sources, not the breakdown of glycogen.

2. Which of the following foods is high in indispensable amino acids?

• A. Lentils
• B. Tofu
• C. Peanuts
• D. Eggs

Correct answer: D

Rationale: The correct answer is D, eggs. Eggs are considered a high-quality protein source as they are rich in indispensable amino acids. Lentils, tofu, and peanuts also contain protein but are not as high in indispensable amino acids as eggs, making them less complete protein sources.

3. The Dietary Guidelines are published and revised by the U.S. Department of Agriculture in association with the:

• A. Department of Health and Human Services.
• B. National Institutes of Health.
• C. National Academy of Sciences.
• D. Food and Nutrition Board.

Correct answer: A

Rationale: The correct answer is A. The U.S. Department of Agriculture collaborates with the Department of Health and Human Services to publish and revise the Dietary Guidelines for Americans. This collaboration ensures that the guidelines encompass both agricultural and health aspects. Choices B, C, and D are incorrect as they are not directly involved in the publication and revision of the Dietary Guidelines. The National Institutes of Health focuses on medical research, the National Academy of Sciences provides independent scientific advice, and the Food and Nutrition Board is a part of the National Academies of Sciences, Engineering, and Medicine.

4. Which nutrient has a protein-sparing effect?

• A. Glycerol
• B. Carbohydrate
• C. Nitrogen
• D. Fatty acids

Correct answer: B

Rationale: Carbohydrates have a protein-sparing effect, meaning that adequate carbohydrate intake can prevent the use of protein for energy. Glycerol, nitrogen, and fatty acids do not have a protein-sparing effect. Glycerol is a component of fats and oils, nitrogen is a component of proteins, and fatty acids are used primarily as an energy source.

5. Which of the following is an example of a complete protein?

• A. Milk
• B. Soy
• C. Sesame seeds
• D. Sweet potato

Correct answer: A

Rationale: The correct answer is A, Milk. Milk is considered a complete protein as it contains all the essential amino acids required by the body. Soy (choice B) is also a complete protein, containing all essential amino acids. Sesame seeds (choice C) and sweet potato (choice D) are not complete proteins as they lack one or more essential amino acids needed by the body.
