identify highly reactive, toxic byproducts of oxygen metabolism. more than one answer may be correct.
h₂o
oh-
h₂o₂
o₂
o₃
o₂-

Explanation:

• \(O_{2}\) (molecular oxygen) is relatively stable under normal physiological conditions and is not a highly reactive, toxic by - product of oxygen metabolism.
• \(O_{3}\) (ozone) is not a by - product of normal oxygen metabolism in cells.
• \(H_{2}O\) (water) is a normal and non - toxic end - product of many metabolic reactions involving oxygen (such as aerobic respiration).
• \(OH^{-}\) (hydroxide ion) is not a major highly reactive, toxic by - product of oxygen metabolism in the context of reactive oxygen species (ROS).
• \(O_{2}^{-}\) (superoxide anion) and \(H_{2}O_{2}\) (hydrogen peroxide) are well - known highly reactive, toxic by - products of oxygen metabolism. Superoxide anion is a free radical, and hydrogen peroxide can be converted into more reactive species like hydroxyl radicals (\(\cdot OH\)) through the Fenton reaction.

Answer:

\(O_{2}^{-}\), \(H_{2}O_{2}\)
