The Sodium Pump Living cells actively "pump" positive sodium ions (Na+) from inside the cell to outside the cell. Th 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 A) Given that the electric potential is 6.4x102 V higher outside the cell than inside the cell, and that the cell membrane is 0.10 um thick, calculate the work that must be done (in joules) to move one sodium ion fronm inside the cell to outside. Express your answer using two significant figures B) If the thickness of the cell membrane is increased, does your answer to part A:? a) increase b) decrease c) stay the same
