The organelle inside of the cell that breaks down toxic chemicals is the

1. Golgi apparatus

2. Lysosome

3. Peroxisome

4. Endoplasmic reticulum

The correct answer is: Peroxisome

The other options listed, the Golgi apparatus, Lysosome, and Endoplasmic reticulum, all serve different functions within the cell and are not responsible for breaking down toxic chemicals. The Golgi apparatus is responsible for modifying, sorting, and packaging proteins for secretion or use within the cell. The Lysosome is responsible for breaking down macromolecules and old cell parts. The Endoplasmic reticulum is responsible for protein and lipid synthesis. The correct answer, the Peroxisome, is responsible for breaking down toxic chemicals and protecting the cell from their harmful effects. It also plays a role in lipid metabolism and the production of hydrogen peroxide.
