Consider the following reaction, which occurs in glycolysis.
fructose 6-phosphate <-> glucose 6-phosphate K?eq = 1.97
(a) What is the ?G°? for the reaction (at 25°C)?
(b) The ?G for the reaction in vivo is +2.5 kJ/mol. Conceptually, what is the difference between a ?G°? and a ?G? What does this given value of ?G tell you about the direction this reaction proceeds in vivo?
(c) What is the ratio of [glucose 6-phosphate]:[fructose 6-phosphate] in vivo? (use T = 25°C)
