The relation between electron transport, proton transport, proton gradient-formation and ATP synthesis is qualitatively and quantitatively investigated. Proton gradients have many properties which are in agreement with their being an intermediary energy pool between electron transport and ATP formation. Approximately three protons are required to transverse the chloroplast-vesiclemembrane to provide sufficient energy for the synthesis of an ATP molecule in the steady state. The system is shown to be fully reversible through the experimental demonstration of ATP driven proton gradients and reverse electron flow, and proton gradient driven reverse electron flow and reverse-electron-flow-luminescence.
