ATP synthase uses a specific stoichiometric ratio of protons to synthesize each ATP molecule
ATP synthase relies on a specific stoichiometric ratio of protons to synthesize ATP, which is determined by the ring structure of its c-subunits and varies in a species-specific manner.
The retrieved papers consistently demonstrate that ATP synthase utilizes a defined stoichiometry of proton-translocating c-subunits to produce ATP, with specific ratios (such as c10, c12, or c13) characterizing different species and mutants. The claim is well-supported by structural and bioenergetic studies.
