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.
What is a citric acid cycle?
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.
