Answer:
Organ: Liver
Explanation:
Ammonia is a toxic waste product that is produced during protein metabolism in the body. It is important to convert ammonia into a less toxic compound before it can be safely eliminated from the body. This conversion takes place in the liver.
Process:
1. Urea Cycle: The liver contains enzymes that are involved in a series of chemical reactions known as the urea cycle. This cycle converts ammonia into urea, a much less toxic compound.
2. Ammonia Conversion: In the urea cycle, ammonia combines with carbon dioxide to form urea. This reaction occurs in several steps involving different enzymes, such as ornithine transcarbamylase, argininosuccinate synthetase, and argininosuccinate lyase.
3. Urea Transport: Once urea is formed, it is transported from the liver to the kidneys through the bloodstream. In the kidneys, urea is filtered out of the blood and excreted in the urine.
4. Kidney's Role: While the kidney plays a crucial role in excreting urea, it is important to note that the conversion of ammonia into urea primarily occurs in the liver.
In summary, the liver is responsible for converting ammonia into urea through the urea cycle. This process enables the body to safely eliminate ammonia as urea, preventing its toxic buildup in the bloodstream.
