    Free Energy of Fructose-6-Phosphate and Glucose-6-Phosphate

    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    Fructose-1,6-diphosphate can be converted to glucose-1-phosphate by three successive reactions:

    Fructose 1,6 diphosphate + H20 ---> fructose-6-phosphate + Pi Keq= 607

    Fructose-6-phosphate ---> glucose-6-phosphate G°= -410 cal/mol

    Glucose-6-phosphate --->glucose-1-phosphate G°= 1750 cal/mol

    Assuming 1 atm pressure, 25°C, R = 1.99cal/mol x deg C. From the above info what is the Keq and the deltaG° for the overall reaction?
