Question

Gibbs Free energy equation. Help, Please.

Intracellular and Extracellular Ion Concentrations for a Typical Mammalian Cell Transmembrane potential Deltapsi= -60 mV, T = 310 K 4. Calculate the Gibbs free energy for transfer of 1 mole of K^+ out of the cell. Describe possible mechanism (via molar ratio of ions) of coupling the transport of K^+ and Mg^2+ into the cell, assuming that the maximum coupling efficiency of 100% (you may use your calculations from Problem #1 for Mg^2+). 5. In the "box in the sea" model, assume 3 cal of heat was transferred from the box to the sea at 310 K. What is the entropy change of the sea (in e.u.)?

Explanation / Answer

Gibbs free energy equation G=H-TS

G= change in Gibbs free energy

H= change in enthalpy

S= change in entropy
