1. Where does most nutrient digestion and absorption occur?
- A. Large intestine
- B. Small intestine
- C. Stomach
- D. Mouth
Correct answer: B
Rationale: The small intestine is the correct answer. It is the primary site for nutrient digestion and absorption in the digestive system. The small intestine plays a crucial role in breaking down carbohydrates, proteins, and fats into forms that can be absorbed by the body. While the large intestine absorbs water and electrolytes, the majority of nutrient absorption occurs in the small intestine. The stomach primarily functions in the initial digestion of proteins, and the mouth begins the mechanical breakdown of food through chewing.
2. Which of the following amino acids are considered indispensable?
- A. Lysine
- B. Methionine
- C. Tryptophan
- D. Valine
Correct answer: A
Rationale: The correct answer is A: Lysine. Indispensable amino acids are those that the body cannot synthesize and must be obtained from the diet. Lysine, methionine, and tryptophan are all examples of indispensable amino acids. However, the question specifically asked for 3 out of the 9 indispensable amino acids, making 'Lysine' the correct choice. Choices B, C, and D are also indispensable amino acids but are not the focus of the question.
