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. Fructose is the sugar found in:
- A. bread.
- B. gelatin desserts.
- C. sugar-coated cereals.
- D. honey and fruit.
Correct answer: D
Rationale: Fructose is a sugar naturally found in honey and fruit. While bread contains carbohydrates, it does not primarily consist of fructose. Gelatin desserts are more likely to contain added sugars like sucrose rather than fructose. Sugar-coated cereals typically contain sucrose or other added sugars, not just fructose. Therefore, the correct answer is honey and fruit as they naturally contain fructose.
3. Which condition may benefit from branched chain amino acids (leucine, isoleucine, and valine)?
- A. cancer-related malnutrition
- B. marasmus
- C. cardiovascular disease
- D. severe depression
Correct answer: A
Rationale: Branched chain amino acids, such as leucine, isoleucine, and valine, are essential in preventing muscle breakdown. Therefore, they may be particularly important for a patient with cancer-related malnutrition, where maintaining muscle mass is crucial. Marasmus is a severe form of malnutrition characterized by energy deficiency, not specifically related to cancer. Cardiovascular disease and severe depression do not have a direct correlation with the need for branched chain amino acids to prevent muscle breakdown.
4. Which of the following enzymes is found in pancreatic secretions?
- A. Rennin
- B. Pepsin
- C. Chymotrypsin
- D. Casein
Correct answer: C
Rationale: Chymotrypsin is an enzyme found in pancreatic secretions that plays a role in protein digestion. Rennin is primarily found in the stomach and is involved in milk digestion. Pepsin is also a stomach enzyme that aids in protein breakdown. Casein is a protein found in milk, not an enzyme involved in pancreatic secretions. Therefore, the correct answer is Chymotrypsin.
5. One characteristic of an essential fatty acid is that it:
- A. comes from a plant source.
- B. comes from an animal source.
- C. is not manufactured by the body.
- D. is manufactured by the body.
Correct answer: C
Rationale: The correct answer is C because essential fatty acids are not manufactured by the body and must be obtained through the diet. Choice A is incorrect because essential fatty acids can come from plant sources as well. Choice B is incorrect as essential fatty acids are primarily derived from plant sources. Choice D is incorrect because essential fatty acids cannot be produced by the body. Therefore, the only accurate statement is that essential fatty acids are not manufactured by the body.
