How does a proton gradient drive the synthesis of ATP?
Adi S.
ATP synthase attaches a phosphate group to ADP, forming ATP. This process requires energy. The energy is provided by electron carrier molecules in the electron transport system that pump protons (H+ ions) into the intermembrane space (also called outer compartment). When these move back into the mitochondrial matrix, they must move through ATP synthase. This movement through ATP synthase provides the power needed by ATP synthase to push the third phosphate group onto ADP.
