Bonjour à tous,je n’arrive pas à calculer le km de cette enzyme. 

Je dois faire une erreur bête dans mes calculs mais je ne l’a retrouve pas.

Salut @Denazare

 

Tu connais la formule : 

Vi = \frac{Vm * S }{Km + S}

 

Tu modifie un peu les termes pr avoir Km à gauche de l'équation:

Km = \frac{Vm * S}{Vi} - S

 

Tu remplaces par les valeurs:

Km =\frac{120 * 40 }{60} - 40 =40 µmol/l
