### Calculating ATP

I am having trouble calculating ATP.

I got this on a quiz:

"Calculate the amount of ATP produced from the FULL oxidation of 3 Acetyl - CoA molecules in the aerobic ATP pathway"

Oxidation of one molecule of acetyl coA is the one Krebs cycle.

In one Krebs cycle, produce 3 NADH, 1FADH2, 1 GTP
1 NADH = 3 ATP x 3
1FADH2 = 2 ATP x 1
1GTP = 1ATP
______________
Total: 12 ATP

U have three acetyl CoA = 3 x 12 ATP = 36 ATP

you are still using the 1 NADH = 3 ATP and 1 FADH = 2 ATP. I thought most books have already changed it to 2.5 and 1.5 conversion
