Assuming no change in either the internal or external calcium ion concentration, at what membrane potential would there be no net movement of calcium across the membrane?
 
  A cell biologist interested in the transport of calcium ions (Ca2+) across the plasma membrane of bacterial cells made the following measurements on bacterial cells at 25C:
 
  Vm = 150 mV Ca2+ outside = 20 mM Ca2+ inside = 0.4 mM
 
  A) 25 mV
  B) 50 mV
  C) 0 mV
  D) +25 mV
  E) +50 mV
