2 FADH2

4 CO2

Detailed explanation-1: -For complete oxidation of a glucose molecule, the Krebs cycle yields 4 CO2, 6NADH, 2 FADH2 and 2 ATPs.
Detailed explanation-2: -Krebs cycle produces the following: Two molecules of carbon dioxide are given off. One molecule of ATP is formed.
Detailed explanation-3: -The net energy output for one glucose molecule from glycolysis through the Krebs cycle is: 4 ATP, 10 NADH + H+, and 2 FADH2.
Detailed explanation-4: -Solution : Oxaloacetic acid is first 4-C compound that takes part in TCA or Kerbs cycle.It combines with Acetyl Co-A to form 6-C compound, i.e., citrate.
Detailed explanation-5: -Decarboxylation takes place twice in the TCA cycle forming two carbon dioxide molecules. Since two cycles are required thus, 2 CO2 molecules are released per cycle and in total 4 carbon dioxide molecules are released for one molecule of glucose in the TCA cycle.
