1. The percentage of the total daily caloric intake for healthy persons that should be supplied by carbohydrate is:
- A. 10% to 35%.
- B. 20% to 35%.
- C. 40% to 55%.
- D. 45% to 65%.
Correct answer: D
Rationale: The correct answer is D: 45% to 65%. Carbohydrates should contribute between 45% to 65% of the total daily caloric intake for healthy individuals to maintain a balanced diet. Choices A, B, and C are incorrect because they suggest lower ranges, which may not provide sufficient energy from carbohydrates for overall health and well-being.
2. A characteristic of saturated fats is that they are:
- A. mostly found in animal products.
- B. solid at room temperature.
- C. composed of many double bonds.
- D. found primarily in vegetable products.
Correct answer: A
Rationale: The correct answer is A: 'mostly found in animal products.' Saturated fats are primarily found in animal products such as meat, dairy, and eggs. They are typically solid at room temperature. Choice B is incorrect because saturated fats are solid at room temperature, not liquid. Choice C is incorrect because saturated fats do not have double bonds; they have single bonds between carbon atoms. Choice D is incorrect because saturated fats are mainly found in animal products, not vegetable products.
3. Where is Vitamin B12 found?
- A. Whole grains.
- B. Nuts.
- C. Meats.
- D. Legumes.
Correct answer: C
Rationale: Vitamin B12 is primarily found in animal-derived foods like meats. Choices A, B, and D are incorrect as whole grains, nuts, and legumes do not naturally contain significant amounts of Vitamin B12. Therefore, the correct answer is 'C: Meats.'
4. 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.
5. Which enzyme is produced by the parotid gland?
- A. Salivary amylase
- B. Sucrase
- C. Maltase
- D. Lactase
Correct answer: A
Rationale: The correct answer is A, Salivary amylase. Salivary amylase is an enzyme produced by the parotid gland that initiates starch digestion in the mouth. It helps break down starch into maltose, a simpler sugar. Choices B, C, and D are incorrect because sucrase, maltase, and lactase are enzymes involved in the digestion of disaccharides like sucrose, maltose, and lactose, respectively, in the small intestine, not in the saliva.
