Which enzyme mentioned plays a role in the neutralization of superoxide radicals? A) Cytochrome c B) Catalase C) Hemoglobin D) Superoxide dismutase
Understand the Problem
The question is asking which enzyme is responsible for neutralizing superoxide radicals among the given options. To address this, we will identify the function of each enzyme listed and determine which one is specifically known for this role.
Answer
Superoxide dismutase
The enzyme that plays a role in the neutralization of superoxide radicals is Superoxide dismutase.
Answer for screen readers
The enzyme that plays a role in the neutralization of superoxide radicals is Superoxide dismutase.
More Information
Superoxide dismutase catalyzes the conversion of superoxide radicals into hydrogen peroxide and oxygen, playing a critical role in protecting cells from oxidative stress.
Tips
A common mistake is confusing the role of superoxide dismutase with that of catalase. While both are involved in dealing with reactive oxygen species (ROS), superoxide dismutase specifically targets superoxide radicals, while catalase breaks down hydrogen peroxide.
