A plot of 1/V versus 1/[S], called a Lineweaver-Burk or double-reciprocal plot, is a useful tool...
aOn a Lineweaer-Burk plot for a competitive inhibitor, the plots for separaterments at different inhabitor will intersect on the 1/Waxis Correct A competitive inhibitor will alter the apparent Kyof an enzyme-substrate combination but will not alter the apparent ax Value. On a Lineweaver-Burk plot for a competitive inhibitor, the plots for separate experiments at different inhibitor concentrations will intersect on the 1/Waxis. The intersection will be at the point Choose one 0 1/[sj = 1 KM and 1,7:0 O 1/[S]...
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.
Biochemistry inhibitors! Pls answer 1 through 11 For each of the following items, indicate whether the item pertains to: • Competitive inhibitor . Uncompetitive inhibitor • Noncompetitive inhibitor • Noncompetitive activator • None of the above Choose only one of the above for each item. 1. Binds to the enzyme-substrate complex only 2. Prevents substrate from binding enzyme 3. Forms inactive El or inactive ESI complex 4. When present, Vmax increases 5. When present, Vmax increases and Km decreases 6....

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?
56. In the lock and key model of substrate binding to enzymes Pprat wnich they work best a the substrate changes its conformation to fit the active site b. the active site changes its conformation to fit the substrate c. the active site is rigid and the substrate must fit exactly d. the substrate binds only to part of the active site In the induced-fit model of substrate binding a. 57. the substrate changes its conformation to fit the active...
35. Plot Lineweaver-Burk Plots (1/V vs. 1/S1) for the equations shown below and show how it changes with increasing inhibitor concentration [1]. Name the type of inhibition. take an ( 1 + LI1 ) [s+ T max
PLEASE JUST HELP WITH #5 In addition to competitive inhibition, there are two other common types of enzyme inhibition. One type is called uncompetitive inhibition. For this mechanism, the inhibitor can only bind to the ES complex and NOT to the free enzyme: 1. kz . E + E+P ES + 1 ESI Follow the following steps (similar, but not identical to problem 2) to derive d[P]/dt for this mechanism. (a) Write the equation for d[P]/dt (b) Write the equation...
