Detailed explanation-1: -While the Krebs cycle does produce carbon dioxide, this cycle does not produce significant chemical energy in the form of adenosine triphosphate (ATP) directly, and this reaction sequence does not require any oxygen.
Detailed explanation-2: -NADP is not formed during the krebs cycle.
Detailed explanation-3: -To summarize, for complete oxidation of a glucose molecule, Krebs cycle yields 4 CO2, 6NADH, 2 FADH2 and 2 ATPs. Each molecule of NADH can form 2-3 ATPs and each FADH2 gives 2 ATPs on oxidation in the electron transport chain.
Detailed explanation-4: -Products and Functions of the Krebs Cycle For one cycle, two molecules of carbon, three molecules of NADH, one molecule of FADH2 and one molecule of ATP or GTP are produced.
Detailed explanation-5: -Carbon dioxide, NADH, FADH2 and GTP (equivalent to ATP) are all products that are generated during the Citric acid cycle. Water is not generated during this cycle. Therefore, the correct answer is 3. water.
