<Li> ATP synthase produces 1 ATP / 3 H. However the exchange of matrix ATP for cytosolic ADP and Pi (antiport with OH or symport with H) mediated by ATP--ADP translocase and phosphate carrier consumes 1 H / 1 ATP as a result of regeneration of the transmembrane potential changed during this transfer, so the net ratio is 1 ATP: 4 H . </Li> <Li> The mitochondrial electron transport chain proton pump transfers across the inner membrane 10 H / 1 NADH + H (4 + 2 + 4) or 6 H / 1 FADH (2 + 4). </Li> <Dl> <Dd> So the final stoichiometry is </Dd> <Dd> 1 NADH + H: 10 H: 10 / 4 ATP = 1 NADH + H: 2.5 ATP </Dd> <Dd> 1 FADH: 6 H: 6 / 4 ATP = 1 FADH: 1.5 ATP </Dd> </Dl> <Dd> So the final stoichiometry is </Dd>
