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 = 4 + 30 + 4 - 2 = 36 mol ATP per glucose
