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

• A. Large intestine.
• B. Gallbladder.
• C. Pancreas.
• D. Liver.

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. To prevent symptoms of fatigue, dehydration, and energy loss, what is the daily recommended minimum intake of carbohydrates?

• A. 130 g.
• B. 230 g.
• C. 330 g.
• D. 430 g.

Correct answer: A

Rationale: The correct answer is A: 130 g. The recommended minimum intake of carbohydrates to prevent fatigue, dehydration, and energy loss is 130 grams per day. Consuming an adequate amount of carbohydrates provides the body with energy and helps prevent symptoms associated with insufficient carbohydrate intake. Choices B, C, and D are incorrect as they suggest higher amounts of carbohydrate intake, which may not necessarily align with the recommended daily minimum intake for preventing symptoms of fatigue, dehydration, and energy loss.

3. What is the main body storage form of carbohydrates?

• A. Glycogen.
• B. Starch.
• C. Fat.
• D. Glucose.

Correct answer: A

Rationale: The correct answer is A: Glycogen. Glycogen is the stored form of carbohydrates in the body, primarily found in the liver and muscles. Starch (choice B) is a carbohydrate storage molecule in plants, not in the human body. Fat (choice C) is a different macronutrient and not the main storage form of carbohydrates. Glucose (choice D) is a simple sugar that serves as an energy source, not the main storage form of carbohydrates.

4. Which of the following provides the best source of nutrients?

• A. specific food combinations.
• B. a variety of foods.
• C. individual foods.
• D. a variety of food supplements.

Correct answer: B

Rationale: A variety of foods is the best source of nutrients because it ensures a balanced intake of all essential nutrients required by the body. Option A, specific food combinations, may not provide all necessary nutrients as relying on only a few types of food may lead to deficiencies. Option C, individual foods, also may not provide a complete range of nutrients necessary for overall health. Option D, a variety of food supplements, is not the best source of nutrients as whole foods are generally more beneficial due to their natural nutrient composition and bioavailability.

5. What is a primary function of macronutrients in the body?

• A. Regulate metabolic processes.
• B. Supply energy.
• C. Maintain homeostasis.
• D. Control cellular activity.

Correct answer: B

Rationale: The correct answer is B: Supply energy. The primary function of macronutrients such as carbohydrates, fats, and proteins is to supply energy for various bodily functions. Choices A, C, and D are incorrect because while regulating metabolic processes, maintaining homeostasis, and controlling cellular activity are essential functions in the body, they are not the primary roles of macronutrients. Macronutrients mainly serve as a source of energy to support daily activities and bodily functions.
