Cell motions use energy stored in two forms: as a transmembrane ion gradient and in the chemical bonds of ATP, the universal cell fuel. ATP synthase is the universal enzyme that uses both of these fuels to either manufacture ATP or to pump protons. I will present a mathematical model that can explain most of the experimental data on this remarkable protein.
