ATP yield of beta-oxidation of 1 mole stearic acid - proteus

[ArchivalUser]

Beta-oxidation of fatty acids is a catabolic process that occurs in the mitochondria. A researcher wants to know the net yield of ATP that can be produced from the beta-oxidation of stearic acid, an 18-carbon fatty acid. Assume that 1 mole of NADH produces 3 moles of ATP, and 1 mole of FADH2 produces 2 moles of ATP. The net ATP yield of beta-oxidation of 1 mole of stearic acid is equal to which of the following?

A. 140 moles of ATP
B. 142 moles of ATP
C. 144 moles of ATP
D. 146 moles of ATP
E. 148 moles of ATP
F. 150 moles of ATP

could you pls explain that?

18 carbon FA yeilds 9 acetyl coA..
each time it produces acetyl coA.. it gives 1NADH and 1FADH2 = 5ATP so total 8 x 5= 40

each acetyl coA gives 12 ATP so total 12 x 9= 108

108+40 = 148
FA needs two high energy bonds to convert to fattyacyl coA initially

so 148-2 = 146
