Web1 mei 2003 · Ion concentrations are in mM. Permeability of the resting cell is PK 1.0, PNa 0.02, and PCl 2.0 (in arbitrary units). An ATP-driven pump extrudes three Na + ions and imports two K + ions per cycle. The resting potential is −80 mV, and the resting volume is 1.0 (arbitrary units). WebFigure 5.16 Electrochemical gradients arise from the combined effects of concentration gradients and electrical gradients. Na + ions are at higher concentration outside the cell, and K + ions are at higher concentration inside of the cell, and yet the inside of the cell has negative net charge compared to the other side of the membrane. This is due to the …
