The toxic effects of the byproducts of oxygen metabolism are reduced by which of the following
A)Catalase
B)Superoxide dismutase
C)Lactase
D)Two of these

Question

Quizplus · Accepted Answer

Catalase and Superoxide dismutase are both enzymes involved in reducing the toxic effects of byproducts of oxygen metabolism. Catalase breaks down hydrogen peroxide into water and oxygen, while superoxide dismutase converts superoxide radicals into hydrogen peroxide and molecular oxygen. Together, these enzymes help to mitigate the damage caused by reactive oxygen species in the body. Lactase is not involved in oxygen metabolism but rather in the breakdown of lactose in milk. Therefore, the correct answer is D, as both A and B are involved in reducing the toxic effects of oxygen metabolism.
