Question
- A. They are too large to be stored.
- B. They are converted to ammonia.
- C. They are toxic and must be excreted.
- D. They are used immediately for protein synthesis.
Answer
The correct option is They are toxic and must be excreted.. This answer is correct because it matches the approved learning objective to explain (HT only) that proteins are digested to amino acids and excess amino acids cannot be stored in the subtopic Maintaining water and nitrogen balance in the body (biology only).
Explanation
The correct option is They are toxic and must be excreted.. They are toxic and must be excreted. is correct because it directly supports the approved learning objective to explain (HT only) that proteins are digested to amino acids and excess amino acids cannot be stored. This belongs to the subtopic Maintaining water and nitrogen balance in the body (biology only) within Hormonal coordination in humans, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Maintaining water and nitrogen balance in the body (biology only).
Common mistake
Misunderstanding Protein Digestion
Students often think that excess amino acids can be stored in the body like carbohydrates or fats.
Emphasize that excess amino acids are not stored and must be converted into other substances, such as ammonia and urea, for excretion.
