The standard free energy change (deltaG naught prime) for glucose 1-phosphate hydrolysis (i.e. glucose 1-phosphate + H2O --> glucose + phosphate) is -20.9 kJ/mol. If glucose and phosphate are both at 4.8 mM, what is the equilibrium concentration of glucose 1-phosphate at 25 deg C? Assume a gas constant of 8.314 J/mol K.

The value of the standard free energy (∆G°’) for the hydrolysis of ATP (ATP + H2O -> ADP + Pi) is relatively difficult to determine because of the small concentration of ATP remaining at equilibrium. The value can be determined from the equilibrium constant of two related chemical reactions. Glucose-6-phosphate + H2O -> glucose + Pi ; k’eq = 270 ATP + glucose -> ADP + glucose-6-phosphate ; K’eq = 890 From this information, calculate the standard free energy of...
