1. 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.

2. Which of the following provides the best source of nutrients?

• A. specific food combinations.
• B. a variety of foods.
• C. individual foods.
• D. a variety of food supplements.

Correct answer: B

Rationale: A variety of foods is the best source of nutrients because it ensures a balanced intake of all essential nutrients required by the body. Option A, specific food combinations, may not provide all necessary nutrients as relying on only a few types of food may lead to deficiencies. Option C, individual foods, also may not provide a complete range of nutrients necessary for overall health. Option D, a variety of food supplements, is not the best source of nutrients as whole foods are generally more beneficial due to their natural nutrient composition and bioavailability.

3. The professional primarily responsible for the application of nutrition science in clinical practice settings is the:

• A. nurse.
• B. physician.
• C. public health nutritionist.
• D. registered dietitian.

Correct answer: D

Rationale: The correct answer is D: registered dietitian. A registered dietitian is a healthcare professional with specialized training in nutrition and dietetics, making them primarily responsible for applying nutrition science in clinical practice settings. Nurses (choice A) and physicians (choice B) may have some knowledge of nutrition, but a registered dietitian has specific expertise in this area. Public health nutritionists (choice C) typically focus on community nutrition and public health programs, rather than clinical practice settings.

4. Foodborne illness may be caused by contamination of food with:

• A. pesticides.
• B. genetically modified ingredients.
• C. microorganisms.
• D. food additives.

Correct answer: C

Rationale: The correct answer is C: microorganisms. Microorganisms, such as bacteria and viruses, are common causes of foodborne illnesses. These pathogens can contaminate food during various stages of production, processing, or preparation. Choice A, pesticides, are chemicals used to control pests and are not a common cause of foodborne illnesses. Genetically modified ingredients, choice B, refer to foods derived from genetically modified organisms (GMOs) and are not inherently linked to foodborne illnesses. Food additives, choice D, are substances added to food to preserve flavor or enhance taste and are not typically the primary cause of foodborne illnesses.

5. What is the term for the production of glucose from protein, lactate, or glycerol?

• A. glycolysis
• B. gluconeogenesis
• C. glycogenolysis
• D. glucogenesis

Correct answer: B

Rationale: Gluconeogenesis is the correct term for the production of glucose from non-carbohydrate sources such as protein, lactate, or glycerol. Choice A, glycolysis, is the process of breaking down glucose into pyruvate. Choice C, glycogenolysis, is the breakdown of glycogen into glucose. Choice D, glucogenesis, is not a recognized term in biochemistry.
