Problem 46
Show why coupling the reaction for the hydrolysis of 1,3 -bisphosphoglycerate to the phosphorylation of \(\mathrm{ADP}\) is energetically favorable. Combine the equations and calculate \(\Delta G\) for the coupled process. You need only give names or abbreviations in your equations not chemical structures.
