Penicillinase, also known as ß-lactamase, is a bacterial enzyme that hydrolyzes and inactivates the antibiotic penicillin. Penicillinase follows simple Michaelis-Menten kinetics and reaches half its maximal rate of 6.8 × 10-10 µmol-min-¹ when the penicillin concentration is 5.2 × 10-6 M. What would happen to the initial reaction velocity, V₁, of penicillinase if the penicillin concentration were 10.4 × 10-6 M? Vo would be greater than Vmax- Vo would approach Vmax. Vo would exactly equal Vmax. Vo would equal half Vmax.
