In a key reaction of glycolysis, dihydroxyacetone phosphate (DHAP) is isomerized into glyceraldehydes 3- phosphate (G3P) by the action of the enzyme triose phosphate isomerase: Because delta G degree, is positive, the equilibrium lies to the left. Calculate the equilibrium constant for this reaction, assuming a temperature of 37 degree C. In the cell, depletion of G3P makes the reaction proceeds. What is the value of delta G if the concentration of G3P is kept at 1/100 of the value...
