In another key reaction in glycolysis, dihydroxyacetone phosphate (DHAP) is isomerized into glyceraldehyde-3-phosphate (GAP):

Because ΔG°′ is positive, the equilibrium lies to the left.

(a) Calculate the equilibrium constant, and the equilibrium fraction of GAP from the above, at 37 °C.

 (b) In the cell, depletion of GAP makes the reaction proceed. What will AG be if the concentration of GAP is always kept at 1/100 of the concentration of DHAP?
