In beta-oxidation, each double bond in a fatty acid prevents the formation of FADH2, leading to less input into the electron transport chain and a reduced ability to signal 'no' to subsequent calorie input.

“every time you have a double bond in a fatty acid you will get nadh produced because that's i think third step of btox station correct me if i'm wrong um but that first step you will lose the fad and it's just not needed because the double bond is already there the fbd is put in as you generate is generated as you put in a double bond which is part of the process of beetrook station so if you're not generating the electron transporting flavor protein you will not be inputting at that point to the coq couple through the electron transporting flavor protein dehydrogenase on the inner surface of the mitochondrial membrane”
