WebMechanism of the F 1 ATP-ase . The ATP synthase operates through a mechanism in which the three active sites undergo a change in binding affinity for the reactants of the ATP-ase reaction, ATP, ADP and phosphate, as originally predicted by Paul Boyer. WebSo basically in mitochondria one pair of H+ produces 1 ATP. In other words due to movement of 2 protons across the membrane of mitochondria ; conformational change in F1 part results in synthesis of 1 ATP molecule from ADP + Pi. whereas in chloroplast 3 H+ produce 1 ATP. That is movement of 3 protons across lumen to stroma through CF1 …
