Question

In Ornithine cycle, which of the following wastes are removed from the blood ?

• A. Urea and urine
• B. Ammonia and urea
• C. CO2 and ammonia
• D. CO2 and urea

Answer 1

Answer: (C)

CO2 and ammonia

Answer 2

The Ornithine cycle, primarily taking place in the liver, is responsible for eliminating two waste products, namely Ammonia (NH3) and Carbon dioxide (CO2), from the bloodstream. Within the liver, specific molecules and enzymes interact with carbon dioxide and ammonia, converting them into urea. This process is commonly referred to as the urea cycle. In each cycle of this process, two ammonia molecules and one carbon dioxide molecule are converted into urea.

So, the correct option is (C): CO2 and ammonia
