1. Which of the following sandwiches is high in saturated fatty acids?
- A. Tuna salad
- B. Grilled cheese
- C. Turkey and sprouts
- D. Peanut butter and jelly
Correct answer: B
Rationale: The correct answer is Grilled cheese because it is high in saturated fatty acids due to the dairy fat content in cheese. Tuna salad, turkey and sprouts, and peanut butter and jelly do not contain as high levels of saturated fatty acids as grilled cheese. Tuna salad typically contains mayonnaise which may contribute to some saturated fat content, but it is generally lower compared to the cheese in grilled cheese. Turkey and sprouts are leaner options, while peanut butter and jelly are higher in unsaturated fats rather than saturated fats.
2. A protein that contains all the essential amino acids in the proper proportions is called:
- A. simple
- B. indispensable
- C. complete
- D. complementary
Correct answer: C
Rationale: A complete protein is the term used to describe a protein that contains all the essential amino acids required by the body in the right proportions. This makes choice C the correct answer. Choice A, 'simple,' is incorrect as it does not reflect the concept of essential amino acids. Choice B, 'indispensable,' while related to importance, does not specifically address the presence of all essential amino acids. Choice D, 'complementary,' is also incorrect as it refers to combining proteins to achieve a complete amino acid profile, rather than describing a protein that already contains all essential amino acids.
3. Why is it important to understand standard serving sizes of foods?
- A. it is easy to eat too much of some nutrients when choosing healthful foods.
- B. serving sizes have generally decreased over the past few decades.
- C. most people have difficulty estimating the amount of food they eat.
- D. food portions need to be weighed to check serving sizes accurately.
Correct answer: C
Rationale: The correct answer is C. Understanding serving sizes is crucial because most people have difficulty estimating the amount of food they eat. It helps individuals accurately track their intake, which is essential for maintaining a healthy diet and avoiding overeating. Choice A is incorrect because the question focuses on portion sizes rather than specific nutrients. Choice B is incorrect as it presents an unsupported claim about serving sizes decreasing. Choice D is incorrect as weighing food portions is not always necessary to check serving sizes; understanding standard serving sizes allows for a more practical approach to portion control.
4. Which phase of metabolism makes growth and repair possible?
- A. digestion
- B. catabolism
- C. anabolism
- D. ketosis
Correct answer: C
Rationale: Anabolism is the phase of metabolism responsible for building up and repairing tissues in the body. It involves processes that require energy to synthesize complex molecules from simpler ones. Digestion (choice A) is the process of breaking down food into simpler substances for absorption. Catabolism (choice B) involves the breakdown of complex molecules into simpler ones with the release of energy. Ketosis (choice D) is a metabolic state where the body uses fat as the primary source of energy, which is not directly related to growth and repair.
5. What is the function of chylomicrons?
- A. Produced in the hepatic system.
- B. Composed of triglycerides and cholesterol only.
- C. Absorbed in the large intestine.
- D. Cleared from the blood by lipoprotein lipase.
Correct answer: D
Rationale: Chylomicrons are particles that transport dietary fats from the small intestine to cells in the body. They are cleared from the bloodstream by lipoprotein lipase, an enzyme that breaks down triglycerides in chylomicrons into fatty acids and glycerol. This process allows fats to be absorbed by the body. Choices A, B, and C are incorrect because chylomicrons are not formed in the hepatic system, they are composed of various lipids including triglycerides and cholesterol, and they are absorbed in the small intestine, not the large intestine.
