ATP is produced upon the transition from the loose to the tight form of the α and β subunit complex of ATP synthase. This process is part of the mechanism by which ATP synthase converts the energy of a proton gradient into the chemical energy stored in ATP. The other options describe processes related to the establishment of the proton gradient or electron transport, but not directly to the formation of ATP by ATP synthase.
