Answer: Peroxisomes 
Explanation: 
These are micro body which is found virtually in all the eukaryotic cells. They are involved in the catabolism of long chain and short chain fatty acid.
They generate the highly reactive oxygen species and it is broken down here only.These molecules are hydrogen peroxide and they are converted into water molecules.
This organelle is known as peroxisomes.
