...Jesper Brahm SUMMARY This study extends permeability ( P ) data on chloride, urea and water in red blood cells (RBC), and concludes that the urea transporter (UT-B) does not transport water. P of chick, duck, Amphiuma means , dog and human RBC to 36 Cl − , 14 C-urea and 3 H 2 O was determined under...

... (external pH 7.0 at both times), thereby providing only hydroxyl ions as a potential anion substrate for exchange with external 36 Cl – . As indicated in this figure,Cl – influx was a sigmoidal function of external chloride concentration at each intravesicular pH condition and followed the Hill equation...

.... Thiocyanate is known to inhibit chloride uptake in a number of freshwater animals and therefore these data suggest that it is only the MR cells that are involved in the uptake of Cl − in brown trout. * Present address: Biology Department, McMaster University, Hamilton, Ontario, Canada, L8S 4K1...

...George A. Gerencser; Soon-Ho Lee The three universally accepted mechanisms of chloride transport across plasma membranes are: (i) sodium-coupled symport; (ii) anion-coupled antiport; and (iii) coupling to primary ion transport through electrical and/or chemical mechanisms. No direct evidence has...
