Electrolyte Distribution and Active Salt Uptake in Frog Skin
1. The "chloride space" in frog skin was determined and found to be 69.7 per cent by weight of wet skin. The chloride space occupies about 94 per cent of the total water space of skin. From this and other information, it appears that the "non-chloride space" measures only a part of the space occupied by the structural elements of skin. This space is referred to here as the intracellular compart...
متن کاملELECTROLYTE DISTRIBUTION AND ACTIVE SALT UPTAKE IN FROG SKIN* Bx ERNST G. HUF,
Essential requirements for the maintenance of active uptake of sodium chloride in isolated frog skin in Ringer's solution are: sufficient oxygen supply (8); neutral or slightly alkaline reaction of Ringer's solution (10); a reasonable temperature, e.g. 25°C., of the environment (10). A few years ago it was found (11) that, in addition to the above mentioned factors, the K + level in Ringer's so...
متن کاملElectrolyte Metabolism of Isolated Frog Skin
A study is presented on the effect of temperature on unidirectional active ion transport, resting electrolyte equilibrium (electrolyte composition), and oxygen consumption in isolated frog skin. The aims were twofold: first, to find out whether the rate of active transport can be changed without affecting the Na + and K + balance of skin itself; second, to arrive at minlmal ANa/AO2 values by co...
متن کاملEffect of Temperature on Electrolyte Metabolism of Isolated Frog Skin
A study is presented on the effect of temperature on unidirectional active ion transport, resting electrolyte equilibrium (electrolyte composition), and oxygen consumption in isolated frog skin. The aims were twofold: first, to find out whether the rate of active transport can be changed without affecting the Na(+) and K(+) balance of skin itself; second, to arrive at minimal DeltaNa/DeltaO(2) ...
متن کاملFluxes and Distribution of Sodium in Frog Skin
The exchange of substances between higher organisms and the environment takes place at the level of epithelial membranes constituted by one or more layers of cells. Experimental models (17, 31, 50) and theoretical analysis (13, 45) generally assume that any molecule going across an epithelial membrane must traverse at least two plasma membranes: one to get into the epithelial cells and another ...
