Phosphoenol Pyruvic Acid

 

Reaction 9:Phosphate Ester Hydrolysis;
Synthesis of ATP

This is the final reaction in glycolysis. Again one of the phosphate groups undergoes hydrolysis to form the acid and a phosphate ion, giving off energy. This first energy producing reaction is coupled with the next endothermic reaction making ATP. The phosphate is transferred directly to an ADP to make ATP.

This reaction is catalyzed by pyruvate kinase.
