The glucose has been broken down in the citric acid cycle is When A-ketoglutarate is oxidized to Succinyl CoA. The correct option is D.
The citric acid cycle is also called the Krebs cycle. It is an aerobic respiration.The reaction converts the cycle acetyl coenzyme A (acetyl CoA) into the reducing power of nicotinamide adenine dinucleotide (NADH).
The oxidation of A-ketoglutarate is to Succinyl CoA is a metabolic flux f the Krebs cycle.
Thus, the correct option is D. When A-ketoglutrate is oxidized to Succinyl CoA.
