How ammonia is formed? Give tlhe site of its formation.

Explanation

### Step-by-Step Solution:

1. **Understanding Ammonia Formation**:
Ammonia is primarily formed as a byproduct of protein metabolism. When proteins are broken down in the body, they are converted into amino acids. The amino acids undergo deamination, a process where the amino group (-NH2) is removed, resulting in the formation of ammonia (NH3).

2. **Site of Ammonia Formation**:
The formation of ammonia occurs mainly in the liver. The liver cells, known as hepatocytes, are responsible for the deamination of amino acids, leading to the production of ammonia.
