Question

Ammonia is the end product of

• A. Glucose breakdown
• B. Fatty acid metabolism
• C. Protein metabolism
• D. Breakdown of biogenic amines

Answer 1

Answer: (C)

Protein metabolism

Ammonia is constantly being liberated as the end product of protein metabolism (transamination and deamination). This ammonia is toxic to the body. So, it is detoxified in the liver of the animals. Ammonia is detoxified to form urea by the orrithine cycle. Urea is far less toxic than ammonia and so, can remain inside the body for a longer period without causing any ill effects inside the body.
