Question

17. Which of the following statements regarding enzyme inhibition is incorrect?
a. Competitive inhibitors have a similar structure to the normal substrate.
b. Competitive inhibitors bind to the active site of an enzyme.
c. Noncompetitive inhibition can be overcome by adding more substrate.
d. Noncompetitive inhibitors do not have a similar structure to the normal substrate.
e. Noncompetitive inhibitors do not bind to the active site of an enzyme.

Answer 1

is that d

Answer 2

I think you made a mistake again! It should be b, cuz the definition for a competitive inhibitor is the inhibitor binding to the active site of an enzyme, blocking the way of a substrate. While a non-competitive inhibitor binds to the regulatory region of the enzyme, thus changing the shape of the active site

Answer 3

regulatory region is sometimes referred as active site as well, so you cannot choose e
