The transamination of a-ketoglutarate leads to the formation of this amino acid a. aspartate b. glutamate c. asparagine d. glutamine e. valine

B. Glutamate

Explanation:

Transamination is a chemical reaction which involves the transfer of an amino group to a ketoacid to form new amino acids.

In biochemistry, transamination is accomplished by  the enzymes known as transaminases / aminotransferases.  

The example of transanimation is the conversion of α-ketoglutarate to glumate amino acid. α-ketoglutarate in body acts as a predominant acceptor of amino-group and produces glutamate on transanimation as a new amino acid.

It accepts the amino group transferred from the amino acid.

Aminoacid + α-ketoglutarate ↔ α-keto acid + Glutamate
