1. Why is fat important in the diet?
- A. It supplies a constant source of vitamins.
- B. It speeds up the digestive process.
- C. It provides satiety.
- D. It stimulates the release of important digestive enzymes.
Correct answer: C
Rationale: Fat is important in the diet because it provides satiety. Fat slows down digestion and absorption, which helps in making you feel full longer. This feeling of fullness is crucial in controlling food intake and managing weight. Choices A, B, and D are incorrect because fat's main role in providing satiety is related to slowing down digestion, not supplying a constant source of vitamins, speeding up digestion, or stimulating the release of digestive enzymes. While some types of fats can provide certain vitamins, the main purpose of fat in satiety is not vitamin supply.
2. The interrelated network of nerves within the gastrointestinal wall that regulates its muscular action is known as the:
- 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. This network of nerves regulates the muscular movements within the gastrointestinal wall. The gastric nerve plexus (choice A) specifically relates to the stomach, not the entire gastrointestinal tract. The biliary nerve plexus (choice B) is associated with the bile ducts and gallbladder, not the regulation of muscular action. The intestinal nerve plexus (choice D) is a general term that doesn't specifically refer to the network of nerves within the gastrointestinal wall.
3. 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.
4. Fructose is the sugar found in:
- A. bread.
- B. gelatin desserts.
- C. sugar-coated cereals.
- D. honey and fruit.
Correct answer: D
Rationale: Fructose is a sugar naturally found in honey and fruit. While bread contains carbohydrates, it does not primarily consist of fructose. Gelatin desserts are more likely to contain added sugars like sucrose rather than fructose. Sugar-coated cereals typically contain sucrose or other added sugars, not just fructose. Therefore, the correct answer is honey and fruit as they naturally contain fructose.
5. What is the recommended dietary intake of protein for adults?
- A. 0.5 g/kg.
- B. 0.8 g/kg.
- C. 1.0 g/kg.
- D. 1.5 g/kg.
Correct answer: B
Rationale: The recommended dietary intake of protein for adults is 0.8 grams per kilogram of body weight. This amount is considered adequate for most healthy adults. Choices A, C, and D are incorrect as they do not align with the generally recommended protein intake for adults.
