ANSWER :
The pyruvate or pyruvic acid is the end product of glycolysis step in both aerobic and anaerobic cellular respiration. But in aerobic mode of respiration, it converted to acetyl CoA within mitochondria of cell via the enzymatic activity of pyruvate dehydrogenase. Acetyl CoA later acts as substrate molecule for Krebs cycle or TCA cycle. Hence option (B) is the correct answer.

Select ALL of the statements that correctly describe the Krebs cycle. A. Pyruvic acid must be converted to acetyl CoA prior to entering the cycle B. The molecule oxaloacetic acid picks up the acetyl group from acetylCoA, and in the last step of the cycle, oxaloacetic acid is regenerated. C. Electrons removed during oxidation steps are picked up by NAD or FAD. D. Each turn of the cycle generates one ATP molecule for a total of two per molecule of...
