Deamination occurs in:

Options

A. Kidney
B. Liver
C. Nephron
D. Both 'A' and 'B'

Answer

**Step-by-Step Solution:**

1. **Understanding Deamination**: Deamination is the process of removing an amino group (NH2) from an amino acid. This process is crucial for the metabolism of proteins.

2. **Identifying the Location**: The question asks where deamination occurs in the body. The primary organ responsible for this process is the liver.

3. **Role of the Liver**: In the liver, cells are involved in the metabolism of proteins. During deamination, the amino group is removed from amino acids.

4. **After Deamination**: Once the amino group is removed, the remaining part of the amino acid can be used for various purposes, such as ATP production, fat production, or carbohydrate production.

5. **Conversion of Amino Group**: The removed amino group (NH2) is converted into ammonia, which is then transformed into urea. Urea is a less toxic compound that is excreted from the body.

6. **Conclusion**: Since the process of deamination occurs in the liver, the correct answer to the question is the liver.

**Final Answer**: Deamination occurs in the liver.
