The enzyme prostaglandin synthase uses aracadonic acid as the substrate and produces product PGG2. Ibuprofin is an inhibitor of this enzyme. What is the Vmax-app in the presence of 10mg/mL ibuprofin (Vo for this is in the third column)?

[S](mM)      PGG2(Vo mM/min)      I (Vo mM/min)

0.5               23.5                              16.67

1.0               32.2                              25.25

1.5               36.9                              30.49

2.5               41.8                              37.04

3.5               44.0                              38.91
