Textbook Question
Chapter 8, Problem 15P
The same enzyme as in Problem 14 is studied in the presence of a different inhibitor (inhibitor B). In this case, two different concentrations of inhibitor are used. Data are as follows:
a. What kind of inhibitor is inhibitor B?
b. Determine the apparent Vmax and KM at each inhibitor concentration.
c. Estimate KI from these data.
14. The steady-state kinetics of an enzyme are studied the absence and presence of an inhibitor (Inhibitor A). The initial rate is given as a function of substrate concentration in the following table:
a. What kind of inhibition (competitive, uncompetitive. or mixed) is involved?
b. Determine Vmax and KM the absence and presence of inhibitor.

What is the importance of glutamic acid in the metabolism of nitrogen from amino acids? (we know therole; it’s used to remove the nitrogen from amino acids so that the remaining carbon skeleton can bebroken down by the “usual” pathways, but what is the important, unique role that only glutamicacid/glutamate can do?)
