Explanation / Answer

2. The citric acid cycle also termed Krebs Cycle is the next step after glycolysis in aerobic respiration. There are series of enzymatic reactions which are used to catalyze the aerobic respiration. During this cycle adenosine triphosphate (ATP) is produced. There are lot of intermediate steps during this cycle. There are 4 oxidation-reduction reactions which take place during this cycle. The enzymes in the Krebs Cycle oxidize the fuel molecules to carbon dioxide the co-enzymes such as NAD+, FAD, and coenzyme Q are reduced in the process. After the reduction of these coenzymes they have to be reoxidized to start the whole process. The reoxidation occurs after transferring their electrons to oxygen.
