ADA is an enzyme which is deficient in a genetic disorder SCID. What is the full form of ADA?
a. Adenosine deoxyaminase
b. Adenosine deaminase
c. Aspartate deaminase
d. Arginine deaminase
The answer is the option (b) Adenosine deaminase
Explanation: Adenosine deaminase, often abbreviated as ADA, is a vital enzyme found in various tissues throughout the body. It is primarily responsible for the conversion of adenosine, a nucleoside that can accumulate in cells, into inosine. This process is essential for maintaining healthy cellular functions and regulating immune responses. ADA plays a significant role in the purine salvage pathway, which recycles purines and ensures a balanced supply of nucleotides necessary for DNA and RNA synthesis. Deficiencies in this enzyme can lead to severe immune disorders, making it an important focus of medical research and treatment.
