Question 1

The initial oxidation (known as $\beta$-oxidation)of a 16 carbon saturated fatty acid produces 8 acetyl-CoA,7 NADH and 7 FADH₂.The process requires an input of 2 equivalents of ATP for the activation of the fatty acid.If the acetyl-CoA is further oxidized to CO₂,what is the net ATP production from the complete oxidation of the fatty acid assuming that all electron carriers are re-oxidized by the electron transport chain?

Accepted Answer

The answer of The initial oxidation (known as $\beta$-oxidation)of a...
