Questions 9 and 10 are linked. 9. An antibiotic is developed that is a close structural analog of a substrate of an enzyme that participates in cell wall synthesis in bacteria. This binding of the antibiotic reduces overall enzyme activity, but such activity can be restored if more substrate is added. The binding of the antibiotic to the enzyme is not via a covalent bond, nor does the enzyme alter the structure of the antibiotic. Which one of the following would best describe this antibiotic?
A.
It is a suicide inhibitor.
B.
It is an irreversible inhibitor.
C.
It is a competitive inhibitor.
D.
It is a noncompetitive inhibitor.
E.
It is an uncompetitive inhibitor.
