The equilibrium constant, Keq, for the isomerization of dihydroxyacetone phosphate (DHAP) to glyceraldehyde 3-phosphate (GAP) is 0.0475 under standard conditions (298 K, 1 atm, pH 7). Calculate ∆G ̊’ for the reaction. What is ∆G’ for the isomerization reaction when the initial concentrations of DHAP and GAP are 2.2 ́ 10-4 M and 2.9 ́ 10-6 M, respectively? Assume a temperature of 298 K. The same enzyme catalyzes the reverse reaction, the isomerization of GAP to form DHAP. Assume the concentration of GAP remains constant at 2.9 ́ 10-6 M. What is the maximum concentration of DHAP that allows the reaction to proceed spontaneously in this direction?
