Deamination occurs in liver to -

Options

A. Make the use of excess amino acid.
B. Synthesise amino acids.
C. Get rid of urea from blood
D. Convert proteins into uric acid.

Answer

**Step-by-Step Solution:**

1. **Understanding Deamination**: Deamination is a metabolic process that involves the removal of an amino group from an amino acid. This process primarily occurs in the liver.

2. **Purpose of Deamination**: The main purpose of deamination is to utilize excess amino acids. When the body has more amino acids than it needs for protein synthesis, it must process these excess amino acids to prevent toxicity.

3. **Conversion to Urea**: During deamination, the amino group (NH2) is removed and converted into ammonia (NH3), which is toxic at high levels. The liver then converts this ammonia into urea through the urea cycle, allowing it to be safely excreted from the body via urine.

4. **Energy Production**: The remaining part of the amino acid, after the removal of the amino group, can be converted into various intermediates that enter metabolic pathways. This process releases energy, which is stored in the form of ATP (adenosine triphosphate).

5. **Final Outcome**: Thus, deamination serves to make use of excessive amino acids, convert toxic ammonia into urea, and produce energy for the body.

**Conclusion**: Deamination occurs in the liver to make use of excessive amino acids and to convert ammonia into urea for excretion.
