Considering the energy changes associated with the individual reactions below, which reaction can be coupled with the hydrolysis of ATP to generate a coupled reaction that is energetically favorable?

Question

Quizplus · Accepted Answer

The reaction of fructose 6-phosphate to fructose 1, 6-bisphosphate has a positive ΔG° of +3.3 kJ/mol. However, the hydrolysis of ATP has a negative ΔG° of -30.5 kJ/mol. By coupling the two reactions, the overall ΔG° would be -27.2 kJ/mol, making the reaction energetically favorable. The other reactions listed have either positive or near-zero ΔG° values, making them unfavorable to couple with ATP hydrolysis.
