Conversion of ammonia to urea is done by _____ Cycle:
Conversion of ammonia to urea is done by _____ Cycle:
- Ornithine cycle
- Arginine cycle
- Fumaric cycle
- Citrulline cycle
The Correct Option is A
Solution and Explanation
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

Excretory products and their elimination
The physiological process of the elimination of metabolic waste from the body is called excretion. The excretory products comprise amino acids, carbon dioxide, urea, uric acid, water, and ammonia. Some of the Molluscs and Echinoderms excrete waste products from the body in the form of amino acids. Ammonia is the foremost excretory product in animals, it is derived from the proteins exists in the food we eat.
