Competitive inhibitor vs Noncompetitive (allosteric) inhibitor.

Draw an enzyme bound to each type of inhibitor. Make it simple, like the 'pac man' enzyme. Draw the substrate in both cases as well, demonstrating that it can no longer bind to the active site.

A) competitive on the left, noncompetitive on the right
B) noncompetitive on the left, competitive on the right
C) both competitive
D) both noncompetitive
