Explanation
The liver is an organ that comes into play after consumption of alcohol, as you can remember excess alcohol consumption can result in liver cirrhosis, where scarring occurs on the liver after continuous exposure to high amounts of alcohol. The urea cycle (also known as the ornithine cycle) occurs in the mitochondria of liver cells and results in the conversion of poisonous ammonia (NH3) to urea ((NH2)2CO) which is then excreted in the urine.
