Question

1. the body is able to detoxify reactive oxygen species thru reactions catalyzed by the following enzymes. reduction of hydrogen peroxide forming oxidized glutathione via glutathione peroxidase enzyme. reduction of hydrogen peroxide forming water via the catalase enzyme. regeneration of reduced glutathione thru the action of glutathione reductase. only a & c are correct. a, b and c are correct.

Explanation:

Step1: Analyze option A

Glutathione peroxidase catalyzes the reduction of hydrogen peroxide to form oxidized glutathione. This is a part of the body's detox - mechanism for reactive oxygen species.

Step2: Analyze option B

Catalase enzyme reduces hydrogen peroxide to form water, which is another important detoxification reaction.

Step3: Analyze option C

Glutathione reductase is responsible for the regeneration of reduced glutathione, which is crucial for the continuous function of the antioxidant defense system. Since all three processes (A, B, and C) are involved in the body's detoxification of reactive oxygen species, the answer is that A, B, and C are correct.

Answer:

E. A, B and C are correct.
