Question
Explain why excess amino acids cannot be stored in the body.
Answer
Excess amino acids cannot be stored because the body does not have a dedicated storage mechanism for them. Instead, they are converted into ammonia through a process called deamination, which is then converted into urea for safe excretion. This process is essential to prevent toxic buildup in the body.
Explanation
This answer is strong because it clearly outlines the process of deamination and the conversion of ammonia to urea, addressing the key concepts of amino acid metabolism. The question tests the understanding of protein metabolism and the body's need to manage nitrogen waste.
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.
