EXP:

Peroxisome is a membrane bound organellel found in all eukaryotic cells.

“Peroxisomes contain a group of enzymes that oxidize a variety of substrates and thereby form hydrogen peroxide.The H2O2 thus formed is efficiently decomposed within the organelle by catalase which is present in high concentration”.

Lysosomes can only form H2O2 - They cannot degrade H2O2.

Remember (also see above explanation)

  • H2O2 is produced as well as destroyed in mitochondria and cytosol.

  • It is produced from superoxide by enzyme SOD.

  • It is destroyed by glutathione peroxidase.
