You have a triglyceride in which the fatty
acids are all saturated, and each fatty acid
is composed of 20 carbon atoms.
Assuming complete oxidation of the
triglyceride, which of the following is a
good approximation of the amount of ATP
produced? For convinence, we will assume
that every NADH + H+ enriches the Proton
Motive force enouch to produce 3 ATP,
while every QH2 (FADH2) from Succinate
Dehydrogenase produces 2 ATP.
