Unformatted text preview: Iso, hypo and hyperosmotic Tonicity: iso, hypo and hyper Carrier mediated transport: Facilitated diffusion (uniport) Exchangers (antiport) Cotransport (symport) Active transport: primary and secondary Ion channels and development of membrane voltages Nernst equation V inout = {RT/zF} x {ln([K out ]/[K in ])} V inout is the voltage across the membrane, inside with respect to outside, and R is the gas constant, T is the absolute temp, z is the valence on the ion and F is the Faraday constant. For all practical purposes, this equation reduces to: V inout (in mV) = 60 log [K out ]/[K in ] Membrane voltage depends on ion conc gradient (outside conc/inside conc) and presence of selective channels Role for Na/K pump and ion channels in the generation of membrane voltage...
