BLACK lipid membranes (BLM) have been found to be useful and realistic models for biological membranes1, showing selective ionic2,3and proton4,5permeabilities, differential negative conductance6,7, the photovoltaic effect8, excitability9, ability to support active transport10and the capacity to interact with leucocytic granules11. Biological membranes may also function in the transport of electrons between redox carriers on opposite sides of the membrane: Mitchell12has advocated the coupling of such electron transfer with transmembrane proton translocation as an essential aspect of energy conservation in the redox process of the respiratory chain in mitochondrial and photosynthetic systems. We describe here a partial model for this process in which electronic charge transfer occurs across a BLM. |
