Make an equation describe the relationship between DeltaG,equilibrium constant and prevailing concentrations of substrates and products of reactions. Using the equation calculate DeltaG of reaction, Glucose 6-P <~~~> Fructose 6-P (Keq = 0.5) when the concentration of Glucose 6-P and Fructose 6-P is 5uM and 2uM respectively. Now calculate DeltaG when concentrations of Glucose 6-P and Fructose 6-P are changed to 5uM and 1uM respectively. By examining the differences in DeltaG explain why it is useful for cells to maintain ratio of products to substrates well below Keq.
