confusing question for me with fatty acid metabolism

Question

which of the following is not a direct product of fatty acid metabolism?

 

Acetly CoA

NADH

FADH2

ATP

None of the above, all are directly produced by the fatty acid metabolism

 

I thought it would be ATP as its produced in the electron transport chain but is that related so it would be none of the above?

Answer 1

I agree. ATP would be an indirect product. After electrons are transferred, ADP is oxidized to form ATP. (This question is definitely related to Biochemistry)

 

Answer 2

FADH2
