Question

Superoxide dismutase is involved in the conversion of

• A. NADP to NADPH
• B. Superoxide to Hydrogen peroxide
• C. Hydrogen peroxide to hyphohalite
• D. FAD to FADH

Hint:

SOD protects cells by converting toxic superoxide radicals into less harmful hydrogen peroxide.

Answer 1

The Correct Option is B

Step 1: Understanding superoxide dismutase.
Superoxide dismutase (SOD) is an important antioxidant enzyme that protects cells from oxidative stress.
Step 2: Reaction catalyzed.
It catalyzes the dismutation of superoxide radicals (\( O_2^- \)) into hydrogen peroxide (\( H_2O_2 \)) and oxygen (\( O_2 \)): \[ 2 O_2^- + 2 H^+ \longrightarrow H_2O_2 + O_2 \]
Final Answer: \[ \boxed{\text{Superoxide to Hydrogen peroxide}} \]
