3. Phosphoryl Group Transfers and ATP

The Free-Energy Change for ATP Hydrolysis Is Large and Negative

Other Phosphorylated Compounds and Thioesters Also Have Large, Negative Free Energies of Hydrolysis

ATP Provides Energy by Group Transfers, Not by Simple Hydrolysis

ATP Donates Phosphoryl, Pyrophosphoryl, and Adenylyl Groups

Assembly of Informational Macromolecules Requires Energy
