Which of the following statements aboutthe TCA cycle is INCORRECT?O a. The TCA cycle can recover much more energythan homolactic fermentation.b. All reactions of the TCA cycle take place in themitochondria.C.The energy released in the TCA cycle is mainlystored in the reduced electron carriers NADH andFADH₂.O d. Under anaerobic conditions the TCA cycle is usedto oxidize pyruvate.Oe. The TCA cycle is also called the citric acid cycleafter the product of the first reaction catalyzed bypyruvate dehydrogenase.

An inventive set of eight reactions makes up the TCA cycle. It is a crucial route that uses a…
