A plot of 1/V versus 1/[S], called a Lineweaver-Burk or double-reciprocal plot, is a useful tool for identifying the type of enzyme inhibition. Modify each graph by dragging the endpoints to show the various types of enzyme inhibition. Competitive inhibition What is the inhibition mechanism for the competitive inhibitor? with inhibitor UNI The inhibitor binds to both free enzyme and enzyme-substrate complexes with identical binding constants. The inhibitor binds only to free enzyme. The inhibitor binds to both free enzyme...
c. Describe the properties of i, competitive inhibitor and ii, noncompetitive inhibitor for this enzyme. Draw Lineweaver Burk plots for each and indicate where you can obtain Km and Vmax values for each plot and how they change with the addition of each type of inhibitor 3
The Lineweaver-Burk plots shown below are for enzyme catalyzed reactions. The reaction without and inhibitor is shown in blue. The reaction with an inhibitor is shown in red. Identify the type of inhibition in each plot. with I with I 1/vo without I without I 1/[S] 1/[S] with without I without I 1/[S] 1/[S] with I without I 1/[S] Problem 4 For each plot above describe how Km and Vmax are affected by the inhibitor.

Michaelis-Menten plot and Lineweaver-Burk plot calculations: Use provided data to generate both M-M and L-B plots. Use scatter plots with markers on Excel: On the M-M Plot: estimate Vmax, KM On the L-B Plot: determine Vmax, KM, keat, kcat/Km. The total enzyme concentration is 5 uM. Graphs can be 1/2 page.

The table below lists initial velocities measured for an enzymatic reaction at different substrate concentrations in the presence and absence of an inhibitor. The enzyme concentration is identical in both reactions. Graph a Lineweaver-Burk plot. What are the apparent values of vmax and km for each experiment? what is the inhibition mechanism If the concentration of inhibitor is 0.5 mM, what is the value of K1?

The following observations come from Lineweaver-Burke plots, based on kinetic data generated from a Michaelis/Menton-type enzyme (E) that catalyzes the hydrolysis of a peptide substrate (S). All data were generated in the presence of 18.0 μM total enzyme. The enzyme-catalyzed reaction has a Km of 3.00 μM and a Vmax of 2.00 μM/sec. The enzyme-catalyzed reaction in the presence of 15.0 μM of Inhibitor A has an apparent Km of 2.25 μM and an apparent Vmax of 1.50 μM/sec. The...
