3-phosphoglycerate is converted to 2-phosphoglycerate by phosphoglycerate mutase within a cell (see reaction equation below). The ĪG'° of this reaction is -4.44 kJ/mole. If within the cell the concentration of 3-phosphoglycerate is 2 mM and the concentration of 2-phosphoglycerate is 100 mM, the actual ĪG of this reaction at 25 °C is _______________ kJ/mol. (Please use 3 significant figures in answer)

The value of ĪG°' for the conversion of dihydroxyacetone phosphate to glyceraldehyde-3-phosphate (GAP) is 7.53 kJ/mol. If the concentration of dihydroxyacetone phosphate at equilibrium is 2.55 mM, what is the concentration of glyceraldehyde-3-phosphate? Assume a temperature of 25.0 °C. The constant R = 8.3145 J/(molĀ·K) [GAP] = mM

In glycolysis, the enzyme phosphoglycerate mutase converts 3-phosphoglycerate (3PG) to 2-phosphoglycerate (2PG). a. The standard free energy change for this reaction at 37°C is +4.4 kJ/mol. Calculate the equilibrium constant. Type out all your work and underline the final answer. You will only receive credit for work that is shown. b. Referring back to part a, if the concentration of 3PG at equilibrium for the reaction is 15.2 mM, calculate the equilibrium concentration of 2PG. Type out all your work and underline the final answer. You will only receive credit for work that is shown.
