Final answer:
The fill-in-the-blanks answer is 'glutamine' for both the first and second blanks, and 'amino' for the third blank, referring to biomedical pathways wherein a-ketoglutaric acid forms glutamine.
Step-by-step explanation:
Molecules of a-ketoglutaric acid and glutamine are made of all the same elements. Glutamine is made up of a-ketoglutaric acid and two ammonia (should be 'amino' but assuming typo) molecules.
This is because in amino acid synthesis, glutamate can add ammonia to a-ketoglutarate to form itself, and glutamine is formed from glutamate by the addition of another ammonia molecule.
