An enzyme-catalyzed reaction follows standard Michaelis-Menten kinetics. If the substrate concentration is equal to 3 times the Michaelis constant (), what is the velocity of the reaction () expressed as a fraction of the maximum velocity ()?
- A.0.25 Vmax
- B.0.50 Vmax
- C.0.75 VmaxCorrect answer
- D.0.90 Vmax
Solution
The Michaelis-Menten equation is . Substituting gives: .
