Mg METAPHOSPHATE ^-INTERIOR OF CELL-^ In the resting cell monovalent cations are in equilibrium across the anion impermeable outer membrane. The equilibrium is readily altered by changing the electrolyte content of the medium. For example, if K+ concentration is raised in the medium, there is a redistribution of ions between the medium and the outer zone of the cell. K+ enters the outer zone and H+ leaves, resulting in an acidification of the medium. This exchange involves only limited numbers of ions however, for the outer zone constitutes only a small fraction of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Shanes, Abraham M.
