Why is converting ammonia into urea useful in humans?
Answer and explanation
Correct answer: Urea is less toxic than ammonia
The governing concept is nitrogenous waste management. Breakdown of amino acids produces ammonia, which is highly toxic, especially to body tissues. In the liver, humans convert ammonia into urea through the urea cycle. Urea is considerably less toxic, can be transported safely in the blood, and is removed by the kidneys in urine. It neither produces oxygen nor digests food or pumps blood, so option A correctly explains the advantage.
