The glucoselglucose-6-phosphate substrate cycle involves distinct reactions of g

Question

The glucoselglucose-6-phosphate substrate cycle involves distinct reactions of glycolysis and gluconeogenesis that interconvert these two metabolites. Assume that under physiological conditions, ATP Consider the following glycolytic reaction catalyzed by hexokinase ATP + glucose-ADP + glucose-6 phosphate = 16.7 kJ/mol ADPand Part A Calculate the equilibrium constant (K) for this reaction at 298 K K-845 Submit My Answers Give Up Correct Part B From the equilibrium constant, calculate the maximum [glucose-6-phosphatel[glucose] ratio that would exist under conditions where the reaction is still thermodynamically favorable [glucose-6-phosphate glucosel Submit My Answers Give Up Incorrect; Try Again; 5 attempts remaining

Explanation / Answer

part B

Equilibrium constant(K) = [glucose-6-phosphate][ADP]/[glucose][ATP]

    [ADP]=[ATP] = 1 mM

Equilibrium constant(K) = [glucose-6-phosphate]*1/[glucose]*1

   845 = [glucose-6-phosphate]/[glucose]

answer: 845
