In the lectures we covered the concepts of cooperativity and allosteric regulation with respect to proteins.  Hemoglobin, which is an oxygen binding protein, exhibits three types of allosteric activity. Discuss in detail the 3 types of allostery and cooperativity exhibited by hemoglobin.

4). The biological species concept defines a species as _____.

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]
