Consider the transport of glucose into an erythrocyte by facilitated diffusion.  When the glucose concentrations are 5 mM on the outside and 0.1 mM on the inside, the free-energy change for glucose uptake into the cell is:  (These values may be of use to you:  R = 8.315 J/mol·K; T = 298 K; 9 (Faraday constant) = 96,480 J/V; N = 6.022×10²³ /mol.)

#Unit 2. Cellular Organization
  1. less than 2 kJ/mol.

  2. about 10 kJ/mol.

  3. about 30 kJ/mol.

  4. about –30 kJoule/mol.
