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. What is the recommended dietary intake of protein for adults?

• A. 0.5 g/kg.
• B. 0.8 g/kg.
• C. 1.0 g/kg.
• D. 1.5 g/kg.

Correct answer: B

Rationale: The recommended dietary intake of protein for adults is 0.8 grams per kilogram of body weight. This amount is considered adequate for most healthy adults. Choices A, C, and D are incorrect as they do not align with the generally recommended protein intake for adults.

3. Consuming 30 g of which nutrient would provide the highest number of kcalories?

• A. Carbohydrates
• B. Fat
• C. Protein
• D. Micronutrients

Correct answer: B

Rationale: The correct answer is B, 'Fat.' Fat provides 9 kcalories per gram, which is more than carbohydrates and proteins that provide 4 kcalories per gram each. Therefore, consuming 30 g of fat would yield a higher number of kcalories compared to the same amount of carbohydrates or proteins. Micronutrients do not significantly contribute to kcalories, making them an incorrect choice in this scenario.

4. What can excessive intakes of dietary protein do?

• A. cause vitamin deficiencies.
• B. impair kidney function.
• C. increase weight loss.
• D. decrease production of indispensable amino acids.

Correct answer: B

Rationale: Excessive intake of dietary protein can lead to impaired kidney function over time. Excessive protein consumption can put a strain on the kidneys as they work to eliminate the byproducts of protein metabolism. This can potentially lead to kidney damage. Choices A, C, and D are incorrect. Excessive protein intake is not directly linked to causing vitamin deficiencies, increasing weight loss, or decreasing the production of indispensable amino acids.

5. Which monosaccharide only occurs naturally in foods in combination with another sugar as a disaccharide?

• A. Fructose.
• B. Galactose.
• C. Sucrose.
• D. Maltose.

Correct answer: B

Rationale: The correct answer is B, galactose. Galactose naturally occurs in foods only when it is combined with glucose to form lactose, a disaccharide found in milk. Fructose is a monosaccharide found in fruits and honey. Sucrose is a disaccharide composed of glucose and fructose, commonly known as table sugar. Maltose is a disaccharide formed by the combination of two glucose molecules.
