Phosphoryl-Group Transfer
• Phosphoryl-group-transfer potential - the ability of a compound to transfer its phosphoryl group
• Energy-rich or high-energy compounds have group transfer potentials equal to or greater than that of ATP
• Low-energy compounds have group transfer potentials less than that of ATP

Transfer of the phosphoryl group from PEP to ADP
• Phosphoenolpyruvate (PEP) (a glycolytic intermediate) has a high P-group transfer potential
• PEP can donate a P to ADP to form ATP
