Plot the data on a Lineweaver-Burk plot (be sure to label axes) b. Determine the Km C. Determine the Vmax d. The second set of velocities represents the rate of the reaction when an inhibitor is added. Plot these data on the same graph as above and detemine the new Km and Vmax and the type of inhibitor (competitive, uncompetitive, non-competitive). e. Can the effects of the inhibitor be over-ridden by adding more substrate? Why?

a. Plot the data on a Lineweaver-Burk plot (be sure to label axes)
b. Determine the Km
c. Defermine the Vmax
d. The second set of velocities represents the rate of the reaction when
an inhibitor is added. Plot these data on the same graph as above
and determine the new Km and Vmax and the type of inhibitor
(competitive, uncompetitive, non-competitive).
e. Can the effects of the inhibitor be over-ridden by adding more
substrate? Why?
The kinetics of an enzyme were analyzed in the absence of inhibitors, as
well as in the presence of Inhibitor A and Inhibitor B. Using the given data
below, construct or calculate the following (Make sure to label graphs
with appropriate axes and equations, and circle final answers):
