In salt depleted crayfish net sodium and proton fluxes were coupled 1:1 as required by the frog skin–turtle bladder model. In addition, three proton pump inhibitors produced equal reductions of both fluxes. It is concluded that the model operates i

The major mechanisms of urea turnover and of active ion transport in osmoregula- tory organs are reviewed. Using published values for the molecular flow through these systems it is possible to estimate the energetic cost of osmotic regulation in hypo

Chloride channels in isolated amphibian skins have been shown to be open (high PCi) when the transepithelial potential (TEP) across the skin is >30 mV, inside positive, and [Cl−] in the external medium is high. In the absence of either of these sig

SUMMARYThe emphasis in this review will be on Na+ absorption across the skin and gills of vertebrates and the gills of crustaceans. However, some recent studies of Cl– uptake, especially in crustaceans, will also be described.

Recently, three proton pump inhibitors were shown to have no effect on proton excretion and little on Na uptake in tapwater-adapted (TW) crayfish, while all three reduced Na–H exchange in salt-depleted (SD) animals. It appeared that the exchange wa

A primary mechanism of amino acid inhibition of intestinal alkaline phosphatase is postulated to be the formation of a dissociable enzyme-amino acid complex at an allosteric zinc site. The degree of inhibition was highly correlated with the Zn2+ stab
