Title: Transfer of ions and electrons across the interface between two immiscible liquids in functioning enzyme membrane systems
Abstract: Abstract Charge transfer across the interface between two immiscible liquids in functioning enzyme membrane systems is studied. During an enzyme reaction at an interface involving charge transfer, the initial potential changes due to the change of the electric double layer charge. In the steady state the currents of direct (enzymic) and reverse charge transfer processes become equal and a new potential distribution is established in the system. The proton transfer from water to octane was experimentally studied during the action of mitochondrial ATPase (F1) adsorbed at the octane/water interface in the presence of 2,4-DNP as proton acceptor. The change of the potential difference was measured as a Volta potential in the circuit containing oil/water interface. In the presence of chlorophyll, electron transfer from water to decane was observed at the interface when there was an electron donor in water and an electron acceptor in decane. The influence of the dielectric permeability of oil on the change of the potential difference is studied experimentally and theoretically.
