State role of liver in urea production.

Answer»

1. Ammonia formed during the breakdown of amino acids is converted into urea in the liver of ureotelic animals. 

2. This conversion takes place by the help of the ornithine / urea cycle. 

3. 3 ATP molecules are used to produce one molecule of urea using the ornithine/ urea cycle. Since, the liver contains carrier molecules and enzymes necessary for urea cycle, it plays a major role in urea production.
