Answer #1

The answer is (d) a-ketoglutaric acid.

The process of synthesis of aminoacids in living oragnams is mainly due to Transamination. During this transamination one amino group transfers form Glutamic acid to a organic acid, the glutamic acid turns in to a-ketoglutaric acid and that organic acid turns in to amino acid. Later a-ketoglutaric acid undergoes transamination and converts again into glucatimic acid.

Glutamic acid + Oxalo acetic acid <===> aspratic acid + a-ketoglutaric acid

Many amino acids are broken down into acetyl CoA, just like fatty acids. However, we typically consider amino acids a lower energy fuel source than fatty acids. Why is this? Hint: there are actually two reasons, one related to the amount of energy that can hypothetically be obtained from breakdown of amino acids, and one related to the nitrogen atom(s).
