When a mixture of glucose 6-phosphate and fructose 6-phosphate is incubated with the enzyme phosphohexose isomerase, the final mixture contains twice as much glucose 6-phosphate as fructose 6-phosphate. Which one of the following statements is MOST correct, when applied to the reaction below (R = 8.315 J/mol·K and T = 298 K)?
Glucose 6-phosphate $\harr$fructose 6-phosphate

Question

When a mixture of glucose 6-phosphate and fructose 6-phosphate is incubated with the enzyme phosphohexose isomerase, the final mixture contains twice as much glucose 6-phosphate as fructose 6-phosphate. Which one of the following statements is MOST correct, when applied to the reaction below (R = 8.315 J/mol·K and T = 298 K)?
Glucose 6-phosphate  $\harr$fructose 6-phosphate

Quizplus · Accepted Answer

Given the final mixture contains twice as much glucose 6-phosphate as fructose 6-phosphate, the reaction does not reach equilibrium at a 1:1 ratio, indicating a non-zero Gibbs free energy change. The positive value suggests the reaction favors the reactants (glucose 6-phosphate) under standard conditions.
