which of the following are highly reactive, toxic byproducts of oxygen metabolism? more than one answer may be correct.
□ water (h₂o)
□ hydroxyl radical (oh⁻)
□ hydrogen peroxide (h₂o₂)
□ superoxide ion (o₂⁻)
□ carbon dioxide (co₂)
□ ozone (o₃)
□ molecular oxygen (o₂)

Explanation:

• Hydroxyl radical (OH⁻): It has an unpaired electron, making it highly reactive.
• Superoxide ion (O₂⁻): Reactive due to its unstable structure.
• Hydrogen peroxide (H₂O₂): Can decompose to release reactive species.
• Ozone (O₃): Highly reactive oxidizing agent.
• Molecular oxygen (O₂): Relatively stable under normal conditions.
• Carbon dioxide (CO₂): Stable under normal physiological conditions.
• Water (H₂O): Stable and not a byproduct of oxygen metabolism in the reactive sense here.

Answer:

Hydroxyl radical (OH⁻), Superoxide ion (O₂⁻), Hydrogen peroxide (H₂O₂), Ozone (O₃)
