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. )
A) less than 2 kJ/mol.
B) about 10 kJ/mol.
C) about 30 kJ/mol.
D) about -30 kJoule/mol.
E) impossible to calculate without knowledge of the membrane potential.
