Glycolysis
4 made - 2 used= 2 ATP substrate level
2 NADH x 2= 4 ATP (enters at complex II)
Pyruvate Decarboxylation
1 NADH x two pyruvate= 2 NADH x 3= 6 ATP
Krebs Cycle
3 NADH x two pyruvate= 6 x 3= 18 ATP
1 GTP x two pyruvate= 2 GTP= 2 ATP
1 FADH2 x two pyruvate= 2 FADH2 x2= 4 ATP
Total: 2+4+6+18+2+4= 36 ATP
