Proton Flux Across Model and Biological Membranes
A major function of biological membranes is to act as barriers to the free diffusion of ions. This is most clearly seen when one considers the consequences if membranes were freely permeable: Chloroplasts and mitochondria would be unable to synthesize ATP, nerve impulses could not be produced, muscles could not function and blood cells would hemolyse. For these reasons, bio physicists have long been interested in the nature of the barrier to ion flux.
