Question

Consider the following reaction catalyzed by Phosphopentose Epimerase at 37 oC.

              Xylulose 5-phosphate      --->     Ribulose 5-phosphate

At equilibrium, the ratio of Xylulose 5-P / Ribulose 5-P = 1/18.85 

The physiological concentration of  Xylulose 5-phosphate is  0.019 mM and the physiological concentration of of Ribulose 5-phosphate is 2.940 mM.

Which direction would the reaction proceed as written under physiological conditions?

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
The physiological concentration of Xylulose 5-phosphate is 0.019 mM and the physiological
concentration of of Ribulose 5-phosphate is 2.940 mM.
