On average how many ATP can be made from each FA DH during the electron transport process?

On average, each fatty acid (FA) double bond (DH) during the electron transport process can yield approximately 1.5 to 2 ATP less than saturated fatty acids, due to the reduced number of FADH2 generated. Specifically, the oxidation of unsaturated fatty acids typically results in fewer ATP because the presence of double bonds alters the pathway of electron transport. Overall, the total ATP yield from fatty acid oxidation depends on the length of the fatty acid chain and the number of double bonds present.
