Consider the transport of K+ from the blood (where its concentration is about 4 mM) into an erythrocyte that contains 150 mM K+.The transmembrane potential is about 60 mV,inside negative relative to outside.The free-energy change for this transport process 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) about 5 J/mol.
B) about 15 J/mol.
C) about 5 kJ/mol.
D) about 15 kJ/mol.
E) impossible to calculate with the information given.
