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...
