Homework Answers
Ans: This reaction is consist of two half reactions. First one is the conversion of ADP into ATP and second one is the conversion of X into Y. So the net DG for the overall reaction is the sum of DG for these two half reactions.
Now DG for conversion of ADP into ATP at standard condition is 30.5 KJ/mol, so the DG for the conversion of X into Y is equal to 57.3-30.5, which is 26.8 Kj/mol.
Now in living cell the DG for ADP to ATP conversion is 57 KJ/mol. So if that's the case than the free energy change for the conversion of X into Y is equal to 0.3 KJ/mol.
So the answer is one of the two i described above.

X + ADP > Y + ATP
