1. Show, using the Michaelis-Menten equation, that when [S] >>> Km, vo = Vmax. Show, using the M-M equation that when [S] <<<Km, vo =[S][Et]kcat/Km. 2. What is Vmax? Provide both a mathematical and written description of Vmax? How can Vmax be experimentally altered? How can we use Vmax to determine the turnover number (kcat) of an enzyme-catalyzed reaction? What is the major challenge of determining Vmax from an Michaelis-Menten plot?

4. The double-reciprocal transformation of the Michaelis-Menten equation, also called the Lineweaver-Burk plot, is given by: 1 Km 1 1 where, the plot of (1/V.) vs (1/[S]) is a linear plot. If you only know the x-axis and y-axis intercepts from this plot, how can you determine Vmax and Km? (A) multiply the reciprocal of the x-axis intercept by -1. (B) multiply the reciprocal of the y-axis intercept by -1. (C) take the reciprocal of the x-axis intercept. (D) take...

You perform a series of enzyme activity assays and then graph the data using a Lineweaver-Burk plot. You determine the X-intercept is at -0.02 mM-1 and the Y-intercept is at 5.0 (mM/sec)-1. Calculate the Vmax and Km for this enzyme. A. Vmax = 0.20 mM/sec; Km = 50.0 mM B. Vmax = 0.20 mM/sec; Km = ‒50.0 mM C. Vmax = 5.0 mM/sec; Km = 0.02 mM D. Vmax = 5.0 mM/sec; Km = ‒0.02 mM
