Question:
\(\alpha\)-Ketoglutarate is precursor of -
\(\alpha\)-Ketoglutarate is precursor of -
Show Hint
Reductive amination of alpha ketoglutarate gives an amino acid.
Updated On: Nov 12, 2026
- glutamic acid
- aspartic acid
- fatty acid
- glycerol
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
\(\alpha\)-Ketoglutarate is a five-carbon intermediate of the Krebs cycle.
Step 2: Reaction
By reductive amination with ammonia, catalysed by glutamate dehydrogenase, it is converted to glutamic acid.
Step 3: Other products
Aspartic acid comes from oxaloacetate, fatty acids from acetyl CoA and glycerol from dihydroxyacetone phosphate.
Final Answer:
\(\alpha\)-Ketoglutarate is the precursor of glutamic acid. \[ \boxed{\text{(A) }\text{glutamic acid}} \]
