1. 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.

2. During the process of deamination, the nitrogen portion of amino acids is converted to:

• A. ammonia.
• B. protein.
• C. purines.
• D. glycogen.

Correct answer: A

Rationale: During the process of deamination, the nitrogen portion of amino acids is converted to ammonia. This occurs in the liver as part of the process to remove excess nitrogen from the body. Choice B, 'protein,' is incorrect as deamination breaks down amino acids rather than synthesizing proteins. Choice C, 'purines,' is incorrect as purines are a type of nitrogenous base found in DNA and RNA, not a product of deamination. Choice D, 'glycogen,' is incorrect as glycogen is a storage form of glucose and not a product of amino acid deamination.

3. 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.

4. What is the interrelated network of nerves within the gastrointestinal wall that regulates its muscular action known as?

• A. gastric nerve plexus
• B. biliary nerve plexus
• C. intramural nerve plexus
• D. intestinal nerve plexus

Correct answer: C

Rationale: The correct answer is C, intramural nerve plexus. The intramural nerve plexus is the interrelated network of nerves within the gastrointestinal wall that regulates its muscular action. The gastric nerve plexus (choice A) specifically pertains to the network of nerves in the stomach, not the entire gastrointestinal wall. The biliary nerve plexus (choice B) is associated with nerve supply in the liver, gallbladder, and bile ducts, not the gastrointestinal wall. The intestinal nerve plexus (choice D) is a general term that may refer to various nerve networks within the intestines but does not specifically address the entire gastrointestinal wall.

5. 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.
