Bonsoir,

 

J'ai un petit soucis pour le QCM 10 item E du pack de poly :

Je trouve en bilan de 2 acétyl-Coa + 2 CO2 + 4NADH + + 2ATP avant l'entré dans le Cycle de Krebs et non 2 acetyl-Coa, 1 CO2, 3 NADH et 2 ATP.

 

Mon raisonnement :

1 Glucose --> 2 pyruvates + 2 ATP + 2 NADH

Et

1 pyruvate --> 1 acétyl-Coa + 1 CO2 + 1 NADH

 

Je ne comprend donc pas pourquoi l'item est compté juste, quelqu'un peut il m'expliquer mon erreur ? 😕
