A substrate-level phosphorylation is when a metabolite transfers a phosphate group to ADP to form ATP. Phosphorylation by ATP is the transfer of a phosphate from ATP to another metabolite. Consider the following reactions. In each a phosphate is hydrolyzed: Phosphoenolpyruvate + H2O = Pyruvate + Pi AG-61.9 kJ/mol 1,3-Bisphosphoglycerate + H2O = 3-Phosphoglycerate + Pi AG' = -49.3 kJ/mol = Phosphocreatine + H2O Creatine + Pi AG' -43 kJ/mol ATP + H2O ADP + Pi AG' = -30.5 kJ/mol Fructose 1,6-bisphosphate + H2O = Fructose 6-phosphate + Pi AG' Glucose 6-phosphate + H2O = Glucose + Pi Glycerol 3-phosphate + H2O = Glycerol + Pi AG' -13.8 kJ/mol = AG = -9.2 kJ/mol = -16.3 kJ/mol U Question 10 Under standard biochemical conditions, which of the following molecules can perform a substrate level phosphorylation in an exergonic reaction?
