Glycolysis is the process by which energy is harvested from glucose by living things. Several of the reactions of glycolysis are thermodynamically unfavorable, nonspontaneous, but proceed when they are coupled with other reactions. A. P. + glucose glucose-6-phosphate + H₂O AG = 3.30 kcal/mol B. P. + fructose-6-phosphate fructose-1,6-bisphosphate + H₂O C. ATP + H₂O → ADP + P₁ Which of the reactions are unfavorable? A B с - A and B A and C B and C Which of the reactions can be coupled so that the overall reaction is favorable? AG = -7.30 kcal/mol AG= AG = 3.90 kcal/mol What is the net change in free energy if one set of reactions from the previous question is coupled so that the overall reaction is favorable? If you selected more than one pair of reactions in the previous question, enter the net change for any one of your selected sets. kcal/mol
