Which antioxidant enzyme system functions by removing hydrogen peroxide from the body by converting it into water and oxygen?
A)superoxide dismutase
B)catalase
C)glutathione peroxidase
D)microsomal enzyme-oxidizing system

Question

Quizplus · Accepted Answer

Catalase is the enzyme system that removes hydrogen peroxide from the body by converting it into water and oxygen. Superoxide dismutase converts superoxide radicals into hydrogen peroxide, which is then removed by catalase or glutathione peroxidase. Glutathione peroxidase can also remove hydrogen peroxide, but it does so by using glutathione as a reducing agent. The microsomal enzyme-oxidizing system metabolizes drugs and other foreign substances in the body, but it does not have a role in removing hydrogen peroxide.
