4. Basic concepts of Michaelis-Menten kinetics. The Michaelis-Menten equation is expression of the relationship between the initial velocity, Vo, of an enzymatic reaction and substrate concentration, [S]. There are three conditions that are useful for simplifying the Michaelis-Menten equation: [S] <<Km; [S] = Km; [S] >> Km. Match each condition with the statement(s) that describe it. TV, Vmox[S] Vo =Vmax m . V Vo - Vmax [S] Km +[S] V. (um/min) max [S] (mm) (a) Doubling [S] will almost double...

Write the equations that describe the Michaelis-Menten and the Lineweaver-Burk double-reciprocal plots. Draw examples of each plot, demonstrating how Km and Vmax can be determined. On the same graphs, draw another plot where the same enzyme-catalyzed reaction is subjected to inhibition by a competitive inhibitor.

Consider the following modification of the Michaelis Menten mechanism: E + S ES rightarrow E + P E + I EI In this mechanism, a second molecule. I, can bind to the free enzyme and prevent (or compete with) the binding of substrate. If the [S] is much greater than [I], would you expect the velocity (d[P]/dt) for this mechanism to be different than for the Michaelis Menton mechanism?

The Michaelis-Menten equation models the hyperbolic relationship
between [S] and the initial reaction rate (V0) for an enzyme
catalyzed, single substrate reaction: E S ES E P. The model can be
more readily understood when comparing three conditions: [S]Km.
Match each statement with the condition that it describes. Note:
\"Rate\" refers to initial velocity (V0) where steady state
conditions are assumed; [Etotal] refers to the total enzyme
concentration, and [Efree] refers to the concentration of free
enzyme.

1. Show, using the Michaelis-Menten equation, that when [S] >>> Km, vo = Vmax. Show, using the M-M equation that when [S] <<<Km, vo =[S][Et]kcat/Km. 2. What is Vmax? Provide both a mathematical and written description of Vmax? How can Vmax be experimentally altered? How can we use Vmax to determine the turnover number (kcat) of an enzyme-catalyzed reaction? What is the major challenge of determining Vmax from an Michaelis-Menten plot?
