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

Because ˆ†Go€² is positive, the equilibrium lies to the lef.
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 ˆ†G be if the concentration of GAP is always kept at 1/100 of the concentration of DHAP?
