2. If an inhibitor competitively inhibits an enzyme, use Michaelis-Menten and Lineweaver-Burk plots to illustrate how...
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.
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 to determine Vinas, KM, kcat, kcat/KM.

The kinetics of enzyme catalyzed reactions can be described the Michaelis-Menten equation and the Eadie-Hofstee equation as shown below: V0 = (-Km) V0 / [S] + Vmax a). Please derive the Eadie-Hofstee equation starting from the Michaelis-Menten equation. b). The Vmax and Km of the enzyme catalyzed reaction can be derived from a plot of V0 versus V0/[S]. Please draw one of these plots and explain how do you use it to derive Vmax and Km. c). Please draw a...
(I need help with part C, Drawing the expected Michaelis-Menten plot; Do NOT draw the Lineweaver-Burk plot. thanks!) 1. Michaelis-Menten kinetics- use the M-M equation to answer the following: a. An enzyme (5 µM) has a Vmax of 450 mM/min. What is kcat? b. When the substrate concentration is 50 mM, the initial velocity (V0) was measured to be 375 mM/min. Under the conditions described above, calculate the KM. c. Draw the expected Michaelis-Menten plot (label your axes and include...

The following data were obtained in an enzyme study: Use these data to construct a Michaelis-Menten plot, a Lineweaver-Burk plot, and an Eadie-Hofstee plot. Fit the data in the L-B and E-H plots and use the fit parameters to determine K_M and v_s in each case. Comment on how well the K_Ms and v_ss agree with each other.
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.
