We conclude that extracellular calcium per se, and not intracellular calcium or Ca 2+ transport, stimulates ferric iron uptake. A high level of extracellular K + also stimulates the uptake, probably via cell membrane depolarization. Na + is not involved in these stimulations of iron uptake. The transient K + effect and continuous Ca 2+ effect seem to be additive." . "1514" . "Biochimica et Biophysica Acta" . . . "RIV/68378050:_____/01:23010313!RIV/2003/AV0/A23003/N" .
