otential difference ΔVΔV exists between the inner and outer surfaces of the membrane of a cell. The inner surface is negative relative to the outer surface. If 2.70×10−20 J2.70×10−20 J of work is required to eject a positive sodium ion (Na+)(Na+) from the interior of the cell, what is the magnitude of the potential difference (in millivolts) between the inner and outer surfaces of the cell?

The value is

Explanation:

From the question we are told that

The workdone is

Generally charge on the positive sodium ion is equivalent to the charge on a proton, the value is

Generally the potential difference between the inner and outer surfaces of the cell is mathematically represented as

=>      

=>    

converting to millivolt

    =>
