Question

Given that the electric potential is 7.5x102 V higher outside the cell than inside the cell, and that the cell membrane is 0.10 m thick, calculate the work that must be done (in joules) to move one sodium ion from inside the cell to outside IP The Sodium Pump Living cells actively "pump positive sodium ions (Na) from inside the cell to outside the cell. This process is referred to as pumping because work must be done on the ions to move them from the negatively charged inner surface of the membrane to the positively charged outer surface. Express your answer using two significant figures. Submit Request Answer Part B If the thickness of the cell membrane is increased, does your answer to part A increase, decrease, or stay the same? O increase decrease stay the same Submit Request Answer

Explanation / Answer

Given,

Electric potential V = 0.075 V

charge of the (Na+), q =1.6*10-19 C

The  work must be done to move one sodium ion frominside the cell to outside is

A) W = Vq = (0.075 V )(1.6*10-19C) = 1.2 x 10-20 J

B) Stay the same

Please rate my answer, good luck...
