I have heard that with glucose you get 2 ATP from glycolysis and 1 NADH(which is = 3 ATP), 2 NADH from pyruvate -> acetyl CoA, 6 NADH and 2 FADH2( each of which is = 2 ATP) from the krebs cycle so that from glucose you get 38 ATP.


I have also heard that an 18 carbon fatty acid gives you 146 ATP.


I have not heard of ATP numbers for amino acids(which can enter in glycolysis, pyruvate -> acetyl CoA, or the Krebs Cycle)


How do fatty acids give you more ATP than glucose?


Does forming nucleotides from Glucose 6 Phosphate give you ATP?


What about Gluconeogenesis? Does that have an investment phase and a payoff phase like glycolysis does?



Does forming fats and phospholipids from acetyl CoA  give you ATP?


Does forming amino acids from intermediates in the Krebs cycle give you ATP?
