1. Nutrients interact in the body to regulate metabolic processes, build and repair tissue, and to:

• A. provide energy.
• B. control cellular wastes.
• C. control hormone levels.
• D. regulate absorption.

Correct answer: A

Rationale: The correct answer is A: provide energy. Nutrients play a crucial role in providing energy for the body's various functions. While they do help in regulating metabolic processes and in building and repairing tissue, the primary function related to energy production. Choices B, C, and D are incorrect as nutrients are not primarily responsible for controlling cellular wastes, hormone levels, or absorption.

2. Which of the following is an example of a disaccharide?

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

Correct answer: D

Rationale: The correct answer is D, Maltose. A disaccharide is formed when two monosaccharides are joined together. Glucose, fructose, and galactose are all monosaccharides, not disaccharides. Therefore, they are not examples of disaccharides.

3. A high blood cholesterol level appears to be associated with the development of:

• A. chronic kidney disease.
• B. coronary heart disease.
• C. Alzheimer’s disease.
• D. Addison’s disease.

Correct answer: B

Rationale: A high blood cholesterol level is associated with an increased risk of developing coronary heart disease. Elevated cholesterol levels can lead to the buildup of plaque in the arteries, increasing the risk of heart disease. Choices A, C, and D are incorrect as high blood cholesterol is not primarily linked to chronic kidney disease, Alzheimer’s disease, or Addison’s disease.

4. The function of Dietary Reference Intakes (DRIs) is to designate nutrient recommendations for:

• A. different ethnic groups.
• B. all individuals.
• C. most people.
• D. most healthy people.

Correct answer: D

Rationale: The correct answer is D. Dietary Reference Intakes (DRIs) are established to provide nutrient recommendations for most healthy people. They are not specific to different ethnic groups (choice A), all individuals (choice B), or most people (choice C). DRIs aim to prevent nutrient deficiencies and chronic diseases in healthy individuals by setting intake levels for various nutrients.

5. The nutrients involved in metabolic regulation and control include minerals, vitamins, and:

• A. amino acids.
• B. carbohydrates.
• C. fats.
• D. water.

Correct answer: D

Rationale: The correct answer is D, water. Water plays a crucial role in metabolic regulation along with vitamins and minerals. While amino acids, carbohydrates, and fats are essential nutrients for various bodily functions, they are not primarily involved in metabolic regulation and control.
