1. In addition to protein, which nutrients contribute to the building and repair of tissue?

• A. Vitamins
• B. Carbohydrates
• C. Fats
• D. Enzymes

Correct answer: A

Rationale: The correct answer is A: Vitamins. Vitamins play a crucial role in tissue building and repair along with protein. Carbohydrates (choice B) are primarily a source of energy and not directly involved in tissue building. Fats (choice C) are important for energy storage and insulation but are not the main contributors to tissue building. Enzymes (choice D) are biological catalysts and do not directly contribute to tissue building and repair.

2. Ketones are produced when:

• A. carbohydrate stores are depleted.
• B. excess protein is consumed.
• C. protein stores are depleted.
• D. fat stores are depleted.

Correct answer: A

Rationale: Ketones are produced when the body uses fat for energy due to the depletion of carbohydrate stores. When carbohydrate stores are depleted, the body turns to fat as its primary source of energy, leading to the production of ketones. Excess protein consumption does not directly lead to ketone production. Similarly, the depletion of protein stores or fat stores is not directly related to the production of ketones.

3. What is necessary for photosynthesis to occur along with carbon dioxide and water?

• A. Glucose.
• B. Nitrogen.
• C. Chlorophyll.
• D. Hydrogen.

Correct answer: C

Rationale: The correct answer is C: Chlorophyll. Chlorophyll is a pigment that is essential for photosynthesis as it absorbs light energy, allowing plants to convert carbon dioxide and water into glucose, a process crucial for plant growth. Glucose (choice A) is produced during photosynthesis and is not an ingredient necessary for the process itself. Nitrogen (choice B) is important for plant growth but is not a direct ingredient for photosynthesis. Hydrogen (choice D) is found in water, which is indeed one of the necessary ingredients for photosynthesis, but chlorophyll is specifically required to capture light energy for the process to occur.

4. 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.

5. With respect to its effect on colon microflora, fiber is considered a:

• A. prebiotic.
• B. probiotic.
• C. functional food.
• D. protective agent.

Correct answer: A

Rationale: The correct answer is A: prebiotic. Fiber acts as a prebiotic by providing a food source for beneficial bacteria in the colon, promoting their growth and activity. This helps maintain a healthy balance of microflora in the gut. Choice B, probiotic, is incorrect as fiber itself does not contain live beneficial bacteria but rather supports their growth. Choice C, functional food, is too broad and doesn't specifically address fiber's role in promoting beneficial bacteria. Choice D, protective agent, is vague and does not directly relate to fiber's specific function in colon microflora.
