Question

In ornithine cycle which of the following wastes are removed from the body ?

• A. $C{O}_2$ and Urea
• B. Ammonia and urea
• C. Urea and urine
• D. $C{O}_2$ and ammonia

Answer 1

The correct option is D $C{O}_2$ and ammonia

Two waste products removed from the blood in the liver by Ornithine cycle are Ammonia ($N{H}_3$) and Carbon dioxide ($C{O}_2$). The liver contains molecules and enzymes which act on the carbon dioxide and ammonia and changes them to urea, being known as the urea cycle. One cycle takes away two molecules of ammonia and one molecule of carbon dioxide.

So, the correct option is 'Carbon dioxide and ammonia'.
