reactionn Where v is the velocity or rate, Vmax is the maximum velocity, Km it Michaelis- Menten constant, and [S] is the substrate concentration ap click to In v (HM/min) a) A graph of the Michaelis-Menten equation is a plot of a reaction's initial velocity (Vo) at different substrate concentrations ([S]) 300 275 250 225 200 175 Vmax 1/2 Vmax First, move the line labeled "Vmax" to a position that represents the maximum velocity of the enzyme Next, move the line labeled "1/2 Vmax" to its correct position 150 Km ichaelis-Menten Curve 125 100 75 50 25 0 Then, move the line labeled "Km" to its correct position 0 10 20 30 40 50 60 70 80 90 100 [SI (HM) Continues below b) Estimate the values for these important constants Number Number Vmax = 11 100 M / min UM Previous Give Up & View Solution V Check Answer () Next Exit- HintExplanation / Answer
Michaelis–Menten equation is used typically in enzymatic reactions.
V = Vmax*[S] / (Km + [S])
Where
Vmax = max rate velocity
[S] = substrate concentration
Km = Michaelis–Menten constant
V = reaction rate
then...
From the graph
Vmax --> 175 micrmoM/min approx...
Therefore, the half Vmax --> 175/2 = 87.5 microM/m
the value of [S] at this point Km
Km (when 87.5 microM/min) = 12 approx microM
