Which of the following statements about the Citric acid cycle is incorrect? The Carbon dioxide produced from the Citric acid cycle is a product of oxidation. That is true. Remember, we have Acetyl CoA going into the Citric acid cycle. We make NADH, FADH2, but we also create energy and Carbon Dioxide by oxidation.
The Citric Acid Cycle oxidizes the Acetyl group of the Acetyl CoA to produce energy. This is true. Oxidation reactions in the Citric Acid Cycle produce Coenzyme NAD+ and FAD. This is not true. We oxidize our Acetyl CoA in order to reduce these 2 to create NADH plus FADH2.
So, this is incorrect. Then finally, the Citric Acid Cycle is part of the common metabolic pathway. Remember, the common metabolic pathway is stages 3 and stage 4 of our food catabolism. The Citric Acid being part of stage 3 means that it is part of the common metabolic pathway. So, this is true.
Right. So here, the only statement that is incorrect would be option C.
