Proton cycling through the mitochondrial phosphate transporter in energy transduction.
The molecular structure of the phosphate carrier of mitochondria is probably controlled by the H+ ion concentration within the matrix. It is supposed that changes in molecular structure affect the H+- and H2PO4- ion transporting function and may be part of the "gating" mechanism in phosphate transport.
