  Peroxisome  Peroxisome is  membrane-bound organelle occurring in the cytoplasm of eukaryotic cells . ... Peroxisomes contain enzymes that oxidize certain molecules normally found in the cell, notably fatty acids and amino acids. Those oxidation reactions produce hydrogen peroxide, which is the basis of the name peroxisome. Typical Animal cell and plant cell Animal cell :    Plant cell:  Introduction :  Peroxisomes were described in 1960 as part of the pioneering work of  Christian RenĂ© de Duve , who developed cell fractionation techniques. De Duve’s method separated organelles on the basis of their sedimentation and density properties, and peroxisomes are denser than other organelles. He later coined the term  peroxisome . De Duve shared the 1974  Nobel Prize  for Physiology or Medicine with  Albert Claude  and  George Palade  for that work. Functions of  p eroxisomes : In animal cell :  Peroxisomes,...
