previous work has shown that all these inorganic cations that can be accumulated in quantity at ph7.0 are taken up by the same carrier , that the uptake of mg ( 2+ ) is almost completely inhibited by anoxia and cyanide ( 0.2mm ) and that in the uptake of mg ( 2+ ) ions a practically equivalent amount of h ( + ) ions is excreted .
