Question

If Vmax for a reaction is 10 μM ⋅ s-1 and the KM  is 0.5 μM, what is the reaction velocity when the substrate concentration is 2 μM?

Expert Solution
Step 1

Enzyme reaction at different substrate concentration can be characterize by Michaelis Menten equation. 

Michaelis Menten equation is

Vo = Vmax * S / (Km +S)

where, Vmax is the maximum velocity in a biochemical reactions. Km is the substrate concentration at which half of Vmax is achieved. Vo is the reaction rate at specific substrate concentration. S is the substrate concentration.
