Please explain why you chose the answer as I do not understand the question. When a mixture of glucose 6-phosphate and fructose 6-phosphate is incubated with the enzyme phosphohexose isomerase (which catalyzes the interconversion of these two compounds) until equilibrium is reached,the final mixture contains twice as much glucose 6-phosphate as fructose 6-phosphate. Which one of the following statements is best applied to this reaction outlined below? glucose 6-phosphate<-->fructose 6-phosphate a. delta G is incalculably large and negative b. delta...

9. One of the important reactions in the biochemical pathway glycolysis is the reaction of glucose-6-phosphate(G6P) to form fructose-6-phosphate (F6P): a) Is the reaction spontaneous or nonspontaneous under standard state conditions? b) Standard state conditions imply the concentrations of G6P and F6P to be 1 M, however, in a typical cell, they are not even close to these values. Calculate ΔG when the concentrations of G6P and F6P are 120 μM and 28 uM respectively, and discuss the spontaneity of...
