A fatty acid that contains 20 carbons will yield 10 molecules of acetyl-CoA. Acetyl-CoA is also referred to as acetyl coenzyme A.

How many molecules of FADH2 are produced by the complete oxidation of one acetyl group by the citric acid cycle?
1
Beta oxidation of these molecules converts them into acetyl-coa which can then enter the Krebs cycle for energy derivation these are?
answer is fatty acids (I had the exact same question in my Ap Test)
Is Co2 released during oxidation of pyruvate to acetyl CoA?
Yes.
What is acetyl alcohol?
I think Acetyl alcohol refers to Acetic acid(CH3COOH), which is a type of Carboxylic acid formed by oxidation of Acetaldehyde.
Why do lipids release more energy than carbohydrates?
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.

Calculate the number of acetyl-SCoA molecules generated by complete B-oxidation of a 12-carbon activated fatty acid?
The answer is 5. An acetyl group (containing two C atoms) is split off the original fatty acyl-SCoA with each repetition of the beta-oxidation spiral. Therefore, the first repetition of the beta-oxidation yields one acetyl-SCoA molecule and a fatty acyl-SCoA molecule that is two carbon atoms shorter than the initial fatty acyl-SCoA. There will be five acetyl-SCoA molecules produced by the fifth repetition.
