Shown below is a Lineweaver-Burke plot displaying the kinetics for an enzyme catalyzed reaction that was conducted with 800 pmol of enzyme in both the absence and presence of a 100 µM concentration of an inhibitor.   What type of inhibition is displayed by this inhibitor?  [drop1] Where on the enzyme molecule, relative to the active site, does the inhibitor most likely bind? [drop2] The effect of this inhibitor can be overcome by increasing the substrate concentration [drop3]
