The apical membrane of the intestinal epithelium of the freshwater prawn,Macrobrachium rosenbergii, has been found to possess an apparently unique allosteric carrier mechanism for the simultaneous cotransport of sodium, chloride, and calcium from mucosal solution to cytosol. Influxes of the two monovalent ions individually were sigmoidal functions of their respective luminal concentrations, and their kinetics followed the Hill equation for homotropic cooperativity between identical binding… CONTINUE READING
