The first reаctiоn in glycоlysis is the phоsphorylаtion of glucose:Glucose + Pi → Glucose-6-phosphаte + H2OThis is a thermodynamically unfavorable process, with ΔG°′ = +13.8 kJ/mol. a) In a liver cell at 37°, the concentrations of both phosphate and glucose are normally maintained at about 5 each. What would be the equilibrium concentration of glucose-6-phosphate, according to the above data?Show all your work for credit. Express your answer to two significant figures and include the appropriate units. b) This very low concentration of the desired product would be unfavorable for glycolysis. In fact, the reaction is coupled to ATP hydrolysis to give the overall reaction:ATP + Glucose → Glucose-6-phosphate + ADP + H+What is ΔG°′ for this coupled reaction?Show all your work for credit. Express your answer to three significant figures and include the appropriate units. c) If, in addition to the constraints on glucose concentration listed previously, the liver cell has [ATP] = 4 mM and [ADP] = 2 mM, what is the theoretical concentration of glucose-6-phosphate at equilibrium at pH 7.4 and 37°C?Show all your work for credit. Express your answer to three significant figures and include the appropriate units.
