Triclosan is a broad-spectrum antibacterial agent used in many household products.
It is structurally similar to polychlorobiphenylol, a substrate that binds to the active
site of the enzyme sulfotransferase. Based on these facts, you can conclude that
triclosan most likely:
lowers the activation energy of chemical reactions.
functions as an enzyme when sulfotransferase is absent.
is a competitive inhibitor.
acts as a noncompetitive inhibitor.
Penicillin is an irreversible inhibitor. What is the name of the enzyme that it inhibits? How does that make penicillin
a useful drug for us?
The nonprotein heme group sits in the active site of the hemoglobin enzyme. The heme group facilitates the reaction of the enzyme and is required to be present for the reaction to occur.
Select the best answer.
Question options:
Heme is an example of allosteric inhibition.
Heme is an example of a product.
Heme is an example of a noncompetitive inhibitor.
Heme is an example of a cofactor
Heme is an example of a competitive inhibitor.
