Starting with 6 Carbon molecules, we will take 1 Carbon and add it to NAD+, to create NADH
Now having 5 Carbon molecules, we will take another Carbon to create another NADH
ADP will be turned into ATP and the 4 leftover Carbons will continue through the cycle
FAD2+ will become FADH2 and NAD+ will become NADH
Finally, the remaining Carbon molecules will be used in the next cycle, to be added to the two from the Acetyl CoA.
