Apotential difference of 123 mv exists between the inner and outer surfaces of a cell membrane. the inner surface is negative relative to the outer surface. how much work is required to eject a positive sodium ion (na+) from the interior of the cell?

Work done,

Explanation:

It is given that,

Potential difference between the inner and outer surfaces of a cell membrane,

The inner surface is negative relative to the outer surface. Let W is the work required to eject a positive sodium ion (Na+) from the interior of the cell. Work done is given by :

q is the charge on electron

So, the work required to eject a positive sodium ion (Na+) from the interior of the cell is . Hence, this is the required solution.
