Sequence of Krebs cycle is

A. α-Ketoglutaric acid ⟶ Isocitric acid ⟶ Oxalosuccinic acid

B. Isocitric acid ⟶ Oxalosuccinic acid ⟶ α-Ketoglutaric acid

C. Isocitric acid ⟶ α-Ketoglutaric acid ⟶ Oxalosuccinic acid

D. Oxalosuccinic acid ⟶ Isocitric acid ⟶ α-Ketoglutaric acid

Answer: Option B

Solution(By Examveda Team)

The sequence of the Krebs cycle is Isocitric acid ⟶ Oxalosuccinic acid ⟶ α-Ketoglutaric acid.
The citric acid cycle (CAC) also known as the Krebs cycle is a series of chemical reactions to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats and proteins.
The cycle harnesses the available chemical energy of acetyl coenzyme A (acetyl CoA) into the reducing power of nicotinamide adenine dinucleotide (NADH).
