Question:
Which among the following represents the process of transamination?
Which among the following represents the process of transamination?
Show Hint
Transamination transfers an amino group from an amino acid to a keto acid.
Updated On: Nov 12, 2026
- \(\alpha\)-ketoglutaric acid + \(\text{NH}_{4}^{+}\) + \(\text{NADPH}_{2}\rightarrow\) Glutamic acid + \(\text{H}_{2}\text{O}\) + NADP
- Glutamic acid + Oxaloacetic acid \(\rightarrow\) \(\alpha\)-ketoglutaric acid + Aspartic acid
- Glutamic acid + \(\text{NH}_{4}^{+}\) + ATP \(\rightarrow\) Glutamine + ADP
- Aspartic acid + \(\text{NH}_{4}^{+}\) + ATP \(\rightarrow\) Asparagine + ADP

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
Transamination is the transfer of the amino group from one amino acid to a keto acid, catalysed by transaminases. A new amino acid and a new keto acid are formed.
Step 2: Identify the reaction
Glutamic acid passes its amino group to oxaloacetic acid. Glutamic acid becomes \(\alpha\)-ketoglutaric acid and oxaloacetic acid becomes aspartic acid.
Step 3: Other reactions
Ketoglutaric acid with ammonium and NADPH is reductive amination. The ATP-driven reactions forming glutamine and asparagine are amidation.
Final Answer:
Glutamic acid with oxaloacetic acid giving ketoglutaric acid and aspartic acid is transamination. \[ \boxed{\text{(B) }\text{Glutamic acid + Oxaloacetic acid} \rightarrow \alpha\text{-ketoglutaric acid + Aspartic acid}} \]
