उत्तर
- Ammonia formed during the breakdown of amino acids is converted into urea in the liver of ureotelic animals.
- This conversion takes place by the help of the ornithine/urea cycle.
- 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.
