Question

Conversion of ammonia to urea is done by _____ Cycle:

• A. Ornithine cycle
• B. Arginine cycle
• C. Fumaric cycle
• D. Citrulline cycle

Answer 1

Answer: (A)

Ornithine cycle

Answer 2

The conversion of ammonia to urea is a vital process in the removal of toxic ammonia from the body. This conversion is done by the urea cycle, also known as the ornithine cycle. In this cycle, ammonia is first converted to carbamoyl phosphate, then to citrulline, and eventually to urea. The urea is then excreted by the kidneys. This process takes place primarily in the liver and helps maintain the body's nitrogen balance.

So, the correct option is (A): Ornithine cycle
