5) The conversion of dihydroxyacetone phosphate (DHAP) to glyceraldehyde-3-phosphate in glycolysis has a AG" value of 7.5 kl/mol, so the reaction should be unfavorable. a) Calculate the equilibrium constant for the reaction, based on this AG" value and assuming a temperature of 37 °C. b) For this reaction to occur spontaneously in the cell, glyceraldehyde-3-phosphate (GAP) levels are kept low. What is the value of AG if the concentration of GAP is kept at 1/100 that of the DHAP.

Question
5) The conversion of dihydroxyacetone phosphate (DHAP) to glyceraldehyde-3-phosphate in glycolysis has a AG"
value of 7.5 kJ/mol, so the reaction should be unfavorable.
a) Calculate the equilibrium constant for the reaction, based on this AG" value and assuming a temperature of 37
°C.
b) For this reaction to occur spontaneously in the cell, glyceraldehyde-3-phosphate (GAP) levels are kept low.
What is the value of AG if the concentration of GAP is kept at 1/100 that of the DHAP.
6) Energy can be harnessed as electrons move from compounds with low reduction potential to those with a
higher reduction potential. This happens many times in the electron transport chain, where O, ultimately accepts
the electrons. Using Table 3.6, determine the AG" for the transfer of electrons from glyceraldehyde-3-phosphate
to produce H,0.
