An inhibitor binds to a site other than the active site of the enzyme. Which statement below correlates with this observation?

Question

a. The inhibition must be irreversible. b. It could be noncompetitive or uncompetitive inhibition. c. It must be a competitive inhibitor. d. It could be irreversible, competitive, noncompetitive or uncompetitive. The data do not relate to the type of inhibition. e. All of the above f. None of the above

Answer 1

a) Not necessarily. It could likely be reversible. No way to know without additional information

b) Yes. It wouldn't be competitive as it doesn't compete directly with the substrate at the recognition site.

c) No. It wouldn't be competitive

d) This would be ok if it didn't include "competitive", so that rules this choice out

e) No

f) No

Answer would be (b)
