Question

Quizplus · Accepted Answer

Glutathione peroxidase is the representative enzyme for selenium, and its physiological role is protection from oxidant damage.

The other choices are:

A) Superoxide dismutase is the representative enzyme for copper and zinc, not selenium. Its physiological role is the conversion of superoxide radicals to hydrogen peroxide and oxygen. Copper is also important for brain and CNS function.
B) Myeloperoxidase is the representative enzyme for iron, not selenium. Its physiological role is the production of hypochlorous acid by neutrophils during immune response.
C) Carbonic anhydrase is the representative enzyme for zinc, not selenium. Its physiological role is the regulation of acid-base balance and carbon dioxide transport.
D) Dopamine monooxygenase is the representative enzyme for copper, not selenium. Its physiological role is the synthesis of norepinephrine from dopamine.
