WebNov 25, 2012 · The committed step of glycolysis is the reaction catalyzed by phophofructokine (PFK) converting fructose-6-phosphate into fructose-1,6- bisphosphate. The reaction is irreversible and secondly, it's the only reaction peculiar to the glycolysis. ... There is no cure for glycolysis because glycolysis is the first step in cellular … WebThis is the first committed step of the metabolic pathway of glycolysis, and thus it is very tightly regulated. AMP binds to PFK at a site distinct from the binding site for fructose 6 …
