QuestionSBA
QuestionChoice
Alanine does not react with oxaloacetate. Instead, the reaction between alanine and α-ketoglutarate forms glutamate which transfers its amino group to oxaloacetate.

d
Alanine + oxaloacetate ↔ pyruvate + aspartate
QuestionChoice
Aspartate is not formed in the reaction between alanine and α-ketoglutarate.

c
Alanine + α-ketoglutarate ↔ pyruvate + aspartate
QuestionChoice
Oxaloacetate is not formed in the reaction between alanine and α-ketoglutarate.

e
Alanine + α-ketoglutarate ↔ oxaloacetate + glutamate
QuestionChoice
This is incorrect as glutamate transfers an amino group to oxaloacetate in the second transamination reaction. The reaction is as follows: Glutamate + oxaloacetate ↔ α-ketoglutarate + aspartate

b
Alanine + oxaloacetate ↔ pyruvate + glutamate
QuestionChoice
The transamination of alanine (an amino acid) results in the transfer of an amino group to α-ketoglutarate, which is an amino-group acceptor, to produce glutamate, a new amino acid.
