@j666 Prends-toi un schéma sous les yeux pour te visualiser un peu mieux le truc :

- réaction 1 ( Glucose -> glucose-6-phosphate par l'hexokinase)

- réaction 3 ( fructose-6-phosphate -> Fructose-1,6-biphosphate par la phosphofructokinase I)

- réaction 10 ( phosphoénolpyruvate -> pyruvate par la pyruvate kinase)

 

C'est bon ?
