Use the Michaelis-Menten equation to calculate the initial velocity for an enzyme with Vmax = 3 micromole/min Km= 2 mM [S] = 4 mM
A) 0.75 micromole/min
B) 1.0 micromole/min
C) 1.5 micromole/min
D) 2 micromole/min
E) 2.5 micromole/min

Question

Quizplus · Accepted Answer

The Michaelis-Menten equation is v0 = (Vmax[S]) / (Km + [S]). Substituting the given values: v0 = (3 * 4) / (2 + 4) = 12 / 6 = 2 micromole/min.
