22. ATP Totals Theoretical Yield:
4 ATP from substrate-level phosphorylation (net)
1 ATP per proton pumped across the inner mitochondrial membrane
3 protons per NADH (10 NADH per glucose = 30 ATP)
2 protons per FADH2 (2 FADH2 per glucose = 4 ATP)
Transport of the NADH formed in glycolysis across the mitochondrial membrane - 2 ATP (total)
Total = = 36 mol ATP per glucose
