Question
In the figure below, the solid line shows the dependence of the rate of an enzyme catalyzed reaction v (mu mol/min) as a function of the substrate concentration [S] (mM). Also shown (dotted line) is the dependence of the rate on substrate concentration in the presence of an inhibitor (at a concentration of 2 mM). Regarding the activity of the enzyme in the absence of the inhibitor (solid line), which of the following conclusions is correct? In the presence of the inhibitor (dotted line), the K_m (apparent K_m) of the enzyme, in units of mM. is: On the basis of the graphs shown above, which of the following statements correctly describes the nature of the inhibitor/inhibition?Explanation / Answer
30. Regarding the activity of enyme (solid line) the following is true,
E) When [S] = 1 mM, v = 1 micromol/min
31. In the presence of inhibitor (dotted line) the following is true for Km,
D) 2.0
32. On the bass of graph, the nature of inhibitor is,
A) The inhibitor is competitive
