Question

The site of production of ADA in the body is:

• A. Osteocytes
• B. Blood plasma
• C. Erythrocytes
• D. Lymphocytes

Answer 1

The correct option is D Lymphocytes

Adenosine deaminase enzyme:
Adenosine deaminase enzyme

• ADA enzyme is synthesised in lymphocytes, which helps in the proliferation of T lymphocytes.
• It converts adenosine to inosine. This step is involved in the metabolism of nucleotides and helps in the recycling of nucleotides.
• This enzyme plays an important role in providing immunity.
• When ADA enzyme producing gene is absent, the cDNA of ADAgene is incorporated into lymphocytes using a retroviral vector and these lymphocytes are injected into the body which produce ADAenzyme.

Final answer:lymphocytes

Summary:
Adenosine deaminase enzyme (ADA)
Adenosine deaminase enzyme (ADA) is synthesised in lymphocytes, helps in proliferation of T lymphocytes.

Final answer: Lymphocytes
