WebPeroxisomes are small membrane-bound organisms found within the cytoplasm of eukaryotic cells. The primary function of peroxisomes is to oxidize certain biomolecules, although peroxisomes have other … A major function of the peroxisome is the breakdown of very long chain fatty acids through beta oxidation. In animal cells, the long fatty acids are converted to medium chain fatty acids, which are subsequently shuttled to mitochondria where they eventually are broken down to carbon dioxide and water. In yeast and plant cells, this process is carried out exclusively in peroxisomes. The first reactions in the formation of plasmalogen in animal cells also occur in peroxisomes.

3.8: Lysosomes and Peroxisomes - Biology LibreTexts

WebPeroxisomes are small, round organelles enclosed by single membranes (so again, they look similar to small vacuoles). They carry out oxidation reactions that break down fatty acids and amino acids. They also detoxify many poisons that may enter the body. Alcohol is detoxified by peroxisomes in liver cells. WebPeroxisomes generate hydrogen peroxide (H 2 O 2), which they then use (via catalase) to oxidize a variety of substrates. By virtue of this function, peroxisomes play an important role in the detoxification of substances that are potentially harmful to the cell. Peroxisomes are biochemically diverse, even within a single cell.
