SOME ASPECTS OF SELECTIVE ABSORPTION

Descripción
Sumario:1. A mechanism exists in Valonia which prevents certain substances (Na, Mg, Ca, SO(4)) from reaching as high a concentration inside the cell as in the sea water which surrounds it. 2. A trapping mechanism also exists which causes K to accumulate in the cell in a concentration far in excess of that found in sea water. Practically all the K in the cell exists in the form of KCl. 3. The concentration of Cl does not differ greatly within and without. 4. These facts are not in harmony with present theories regarding the accumulation of K in living cells.
