title: Ion tracer flows and flux ratios in heterogeneous membranes.
abstract: Ion tracer flows and flux ratios at various electrical potentials were studied in heterogeneous membranes comprising parallel pathways of different intrinsic resistance. The total resistance to net flow exceeded the tracer exchange resistance, and the flux ratio was abnormal, as in exchange diffusion commonly attributed to a mobile carrier.
