If the Enzyme Phosphohexoisomerase Is Added to a 0

Multiple Choice

If the enzyme phosphohexoisomerase is added to a 0.3 M solution of fructose 6-phosphate, and the reaction is allowed to proceed to equilibrium, the final concentrations are 0.2 M glucose 6-phosphate and 0.1 M fructose 6-phosphate. These data give an equilibrium constant of 2. What is the equilibrium constant if the initial concentration of fructose 6-phosphate is 3 M?

A) 2
B) 3
C) 5
D) 10
E) 20
