Verified step by step guidance
1
Identify the function described: inactivating toxins by oxidizing harmful substances and breaking down hydrogen peroxide.
Recall the roles of the listed organelles: Lysosomes digest macromolecules, Rough ER synthesizes proteins, Golgi apparatus modifies and sorts proteins.
Understand that the organelle responsible for detoxification and breaking down hydrogen peroxide is the Peroxisome.
Recognize that Peroxisomes contain enzymes like catalase that convert hydrogen peroxide (H2O2) into water and oxygen, neutralizing its harmful effects.
Conclude that the Peroxisome is the organelle primarily responsible for inactivating toxins through oxidation and breakdown of hydrogen peroxide.
