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. What is the most prevalent dietary disaccharide?
- A. Lactose
- B. Fructose
- C. Sucrose
- D. Galactose
Correct answer: C
Rationale: Sucrose is the correct answer as it is the most common disaccharide found in the diet, commonly known as table sugar. Lactose is a disaccharide found in dairy products, not as prevalent in the overall diet as sucrose. Fructose is a monosaccharide commonly found in fruits and honey, not a disaccharide. Galactose is a monosaccharide commonly found in dairy products and is not the most prevalent dietary disaccharide.
3. People with phenylketonuria should avoid foods made with which nonnutritive sweetener?
- A. acesulfame-K
- B. aspartame
- C. saccharin
- D. sucralose
Correct answer: B
Rationale: People with phenylketonuria should avoid aspartame because it contains phenylalanine, which they cannot metabolize. Acesulfame-K, saccharin, and sucralose do not contain phenylalanine and are safe for individuals with phenylketonuria. Therefore, the correct answer is B. Acesulfame-K, saccharin, and sucralose are incorrect choices because they do not pose a risk for individuals with phenylketonuria due to the absence of phenylalanine in their composition.
4. What are the compounds in soy foods with estrogen-like activity examples of?
- A. Indispensable amino acids.
- B. Phytochemicals.
- C. Neurotransmitters.
- D. Metabolic by-products.
Correct answer: B
Rationale: The correct answer is B: Phytochemicals. Phytochemicals in soy foods can mimic estrogen and may have health benefits. Indispensable amino acids are essential amino acids that the body cannot produce on its own. Neurotransmitters are chemical messengers in the nervous system. Metabolic by-products are substances produced during metabolism.
5. 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.
