Consider the following reaction catalyzed by Phosphopentose Epimerase at 37 °C. Xylulose 5-phosphate ---> Ribulose 5-phosphate At equilibrium, the ratio of Xylulose 5-P/Ribulose 5-P = 1/18.85 Calculate AGº Type your answer...

If 0.1 M glucose-1-phosphate is incubated with phosphoglucomutase, the glucose-1-phosphate is transformed to an isomer. At equilibrium, the concentration of glucose- 1-phosphate is 4.5 x 10'M and that of the isomer is 8.6 x 10 M. Calculate K' and AGo" for this reaction (i.e., in the direction of product formation). (R = 8.314 J/mol K)
