Question

Quizplus · Accepted Answer

Peroxisomes are responsible for removing harmful reactive oxygen species (ROS) that accumulate in the cell due to oxidative stress. They contain enzymes such as catalase and peroxidase that break down ROS into harmless byproducts like water and oxygen. This is essential for maintaining cellular homeostasis and preventing damage to other organelles like the mitochondria, which produce ROS as a byproduct of cellular respiration. Therefore, peroxisomes are the most important organelle in responding to oxidative stress in the cell.
