The amount of energy released by any biomolecules is determined by how many ATP molecules are generated after the oxidation of that biomolecule, because the energy released during oxidation is saved in the form of ATP molecules. A glucose molecule on oxidation yields total 38 molecules of ATP that are formed after glycolysis, TCA Cycle and ETS. The number of carbon atoms in glucose is 6. Now consider a 6 Carbon Fatty acid molecule. It will undergo two beta oxidation cycles and will yield 3 Acetyl CoA molecules. Now, in each step of beta oxidation one NAD molecule is converted into NADH and H+ and one FAD molecule is reduced in FADH2. When these NADH and FADH2 molecules release their electrons in the Electron Transport Chain, they together cause the formation of 4 ATP molecules. Thus each step of beta oxidation will lead to formation of 4 ATP molecules. Thus if there are two steps of beta oxidation then there are 8 molecules of ATP. Now the three Acetyl CoA molecules formed also enter the TCA cycle and each cycle will lead to generation of 30 more ATP molecules. Thus, totally, 38 ATP molecules are formed. The number of ATPs formed, goes on increasing as the number of carbons in the fatty acid molecules is increased.
Two ATP molecules are produced from one FADH2 going through the electron transport chain. For every NADH, three ATP molecules are produced.

From glycolysis two pyruvates are produced per molecule of glucose. Pyruvate is converted to acetyl CoA which enters the Kreb's cycle. Therefore, one molecule of glucose eventually creates 2 turns of the Krebs cycle. The cycle produces 1 ATP, 3 NADH, and 1 FADH2 per turn. So for each molecules of glucose you will have 2 FADH2.
Six oxygen molecules are released when one glucose molecule is formed.
12 water molecules are made.
