Non-local thermodynamic effects and efficiency of oxidative phosphorylation.

A non-equilibrium thermodynamic model of oxidative phosphorylation is formulated, which allows us to take into account some non-local effects. In this way, we compute the influence of the tangential resistivity of the inner mitochondrial membrane to proton current, as well as that of the distance between active sites, on the stoichiometry and efficiency of energy conversion.
