Netteta. Plot the data on a Lineweaver-Burk plot (be sure to label axes) b. Determine the K m c. Determine the V max 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 K m and V max and the type of inhibitor (competitive, uncompetitive, non ...
NettetThe Lineweaver-Burke (L-B) plot estimated values of K m and V max were 727 μM and 14.29 units for geraniol and 200 μM and 20 units for acetyl CoA, respectively . The Michaelis-Menten (M-M) plot showed the K m and V max , respectively as 775.1 μM and 16.20 units for geraniol and 190.6 μM and 20.52 units for K m and V max for acetyl CoA.

Nettet5. mar. 2024 · For a Lineweaver-Burk, the manipulation is using the reciprocal of the values of both the velocity and the substrate concentration. The inverted values are then plotted on a graph as 1 / V vs. 1 / [ S ]. Because of these inversions, Lineweaver-Burk plots are commonly referred to as ‘double-reciprocal’ plots. gaia healersNettetLineweaver–Burk plots of 1/V versus 1/[cAMP] for PDE4A display non-classical kinetic behaviour over a wide range of substrate concentrations (0.05–1000 μM) as evidenced by a slight downward curvature as the concentration of substrate is increased (Fig. 13.8A,B).This result is consistent with the presence of at least two non-independent … gaia health retreat saleNettetExercise 3.44.
