Problem: A potential difference of 100 mV exists between the inner and outer surfaces of a cell membrane. The inner surface is negative relative to the outer surface.
Part A: How much work is required to eject a positive sodium ion (Na+) from the interior of the cell?
Please also explain, thank you in advance.
