Which organelle is responsible for detoxifying peroxides within a cell?

Peroxisomes are specialized organelles found within eukaryotic cells that play a crucial role in the detoxification of harmful substances, particularly hydrogen peroxide (H2O2). They contain various enzymes, including catalase, that facilitate the breakdown of hydrogen peroxide into water and oxygen. This process is vital because hydrogen peroxide is a byproduct of various metabolic reactions and can be toxic to the cell if allowed to accumulate.

The mitochondria primarily function in energy production through cellular respiration, while the nucleus serves to store and protect genetic material and regulate gene expression. Lysosomes are involved in breaking down waste materials and cellular debris through enzymatic digestion but do not specifically target peroxides. Therefore, peroxisomes are the organelles that are specifically equipped to handle the detoxification of peroxides, making them the correct answer.
