1. Which body organ is responsible for the metabolic processing of glucose?

Correct answer: D

Rationale: The correct answer is the liver. The liver plays a central role in glucose homeostasis by metabolically processing glucose. The large intestine is primarily involved in absorbing water and electrolytes, not glucose. The gallbladder stores bile produced by the liver but is not directly involved in glucose metabolism. Although the pancreas produces insulin, a hormone that regulates blood sugar levels, the liver is mainly responsible for the metabolic processing of glucose.

2. It has been generally accepted that the percentage of total daily calories supplied by fats should be no more than:

Correct answer: C

Rationale: The recommended fat intake is between 20% to 35% of total daily calories. This range is considered optimal for maintaining a healthy diet. Choice A (10% to 15%) is too low and might not provide enough essential fats for the body. Choice B (10% to 35%) includes an upper limit that exceeds the generally accepted range. Choice D (40% to 55%) suggests a fat intake that is higher than what is recommended, which could lead to health issues if consumed regularly.

3. What is one function of essential fatty acids?

Correct answer: A

Rationale: Essential fatty acids play a crucial role in improving skin integrity by supporting the structure and function of cell membranes. This helps in maintaining healthy skin and promoting overall well-being. The other choices are incorrect because essential fatty acids do not directly control lipid digestion, reduce blood clotting time, or form chylomicrons.

4. What is a major function of glucose?

Correct answer: A

Rationale: Glucose serves as a primary source of energy for the body, especially for the brain and muscles. Choice B is incorrect because glucose itself is not responsible for transporting oxygen to cells. Choice C is incorrect as glucose is converted to glycogen, not the other way around. Choice D is incorrect as glucose itself does not play a direct role in maintaining body weight.

5. The Dietary Guidelines are published and revised by the U.S. Department of Agriculture in association with the:

Correct answer: A

Rationale: The correct answer is A. The U.S. Department of Agriculture collaborates with the Department of Health and Human Services to publish and revise the Dietary Guidelines for Americans. This collaboration ensures that the guidelines encompass both agricultural and health aspects. Choices B, C, and D are incorrect as they are not directly involved in the publication and revision of the Dietary Guidelines. The National Institutes of Health focuses on medical research, the National Academy of Sciences provides independent scientific advice, and the Food and Nutrition Board is a part of the National Academies of Sciences, Engineering, and Medicine.
