Question

In which part of alimentary canal is $N{H}_3$ produced during the digestion of food?

• A. Caecum
• B. Liver
• C. Intestine
• D. Stomach

Answer 1

Answer: (C)

The major contributor to plasma ammonia is the intestine. Intestinal ammonia is derived via two major mechanisms. First, ammonia is liberated from urea in the intestinal lumen by enzymes known as ureases. Ureases are products of many bacteria and convert urea to ammonia and carbon dioxide. Second, after proteins are digested by either host or bacterial proteases, the further breakdown of amino acids generates free ammonia.

So, the correct option is 'Intestine'.
