The blood glucose level is maintained at 5.00 mM. The concentration of glucose in the cytosol of a red blood cell is 0.43 mM. What is change in free energy associated with transporting 1 mole of glucose from the plasma into he cytosol of the red blood cell at 37 degrees Celsius? F=96500 J/mol x V, R= 8.3145 J/molK. The transmembrane electrical potential is -60mV (Plasma to cytosol).
