Deamination occurs in `:`

Options

A. Kidney
B. Liver
C. Nephron
D. Both ( l) and(2)

Answer

**Step-by-Step Solution:**

1. **Understand the Process of Deamination**: Deamination is a metabolic process where excess amino acids in the body are converted into usable by-products. This process is essential for the removal of excess nitrogen from amino acids.

2. **Identify the By-products**: During deamination, the amino group (NH2) from the amino acids is removed and converted into ammonia (NH3). This ammonia is toxic to the body and needs to be processed further.

3. **Role of the Liver**: The liver plays a crucial role in detoxifying ammonia. It converts ammonia into urea, which is much less toxic and can be safely transported in the bloodstream.

4. **Role of the Kidneys**: Once urea is formed in the liver, it is transported to the kidneys. The kidneys filter the blood and excrete urea in the urine, thus removing it from the body.

5. **Conclusion**: Since deamination involves both the liver (where ammonia is converted to urea) and the kidneys (where urea is excreted as urine), the correct answer to the question is that deamination occurs in both the liver and the kidneys.

**Final Answer**: Deamination occurs in both A and B (i.e., kidney and liver).
