Affinity of ADP
« on: January 16, 2011, 09:52:56 AM »
The ∆Go’ of the reaction acetyl phosphate + ADP ⇌ acetate +ATP is -2.8 kcal/mol. Molecule for molecule, acetyl phosphate has (greater, lesser, equal) free energy than does ATP relative  to its dephosphorylated compound; ADP has (greater, lesser, equal) affinity for phosphate than acetate. Circle the correct answer.

I believe the first answer is equal, because acetyl phosphate + ADP is the same as ATP, and I think the answer to the second part is greater. Is this correct?
