Question

Which of the following is true for Krebs cycle?

• A. Isocitrate$\to$ Fumrate$\to$ $\alpha$ ketoglutarate
• B. $\alpha$ Ketoglutarate$\to$ Oxalosuccinate$\to$ Isocitrate
• C. Oxalosuccinate$\to$ Isocitrate$\to$ $\alpha$ ketoglutarate
• D. Isocitrate$\to$ $\alpha$ ketoglutarate$\to$ Succinate

Answer 1

The correct option is D Isocitrate$\to$ $\alpha$ ketoglutarate$\to$ Succinate

In citric acid cycle, isocitrate gets converted into ketoglutarate by decarboxylation reaction which further undergoes second decarboxylation to form succinate.
