Based on the total concentration of charge on each side of the cell, the outside of the cell has
positive charge than the inside of the cell.
Remember that ions are electrically attracted to particles of opposite charge and are repelled by particles of the same charge. By electrical attraction

other large molecules)
Only specific charged particles can pass
These three gradients exist because the plasma membrane is
through
protein such as the voltage-gated Na channel and only when the channel is open.
The following table presents the concentrations of these three solutes inside and outside the cell.
