So initial velocity equal to maximum velocity multiplied and substrate concentration over km plus substrate concentration.
How is Vmax value calculated?
The rate of reaction when the enzyme is saturated with substrate is the maximum rate of reaction, Vmax….plotting v against v / [S] gives a straight line:
- y intercept = Vmax.
- gradient = -Km.
- x intercept = Vmax / Km.
How do you find the Km and Vmax of a Michaelis Menten graph?
From the graph find the maximum velocity and half it i.e. Vmax/2. Draw a horizontal line from this point till you find the point on the graph that corresponds to it and read off the substrate concentration at that point. This will give the value of Km.
How do you calculate Vmax and Km from Michaelis Menten in Excel?

So this one is B 2 divided by 2 then that point second point isMoreAnd then half of VMAX on the y-axis. So this one is B 2 divided by 2 then that point second point is another set of coordinates. That is on the x-axis the km value and on the y-axis.
Is km half of Vmax?
By definition, the KM is the concentration in substrate that gives a rate that is EXACTLY Vmax / 2 (half the Vmax), hence the other name of Km which is half-saturation constant.
How do you calculate Vmax from a Lineweaver Burk plot?

What is Vmax measured in?
umol/min Vmax "represents the maximum rate achieved by the system, at maximum (saturating) substrate concentrations" (wikipedia). Unit: umol/min (or mol/s).
What is the Vmax?
Vmax is the reaction rate when the enzyme is fully saturated by substrate, indicating that all the binding sites are being constantly reoccupied. From: Introduction to Biological and Small Molecule Drug Research and Development, 2013.
