Peroxisome Functions in Cells

Peroxisomes are specialized organelles found in fungi, plant, and animal cells. Their number, size, shape, and activity can change with the tissue type and the cell’s nutritional state. Cells with active lipid metabolism, such as adipocytes, neurons, and hepatocytes, often contain more peroxisomes than other cells.

Eukaryotic cells have multiple, membrane-bound structures called peroxisomes containing digestive enzymes that help oxidize organic molecules.

The shape, number,  and size of peroxisomes vary according to cell type and environmental signals. For example, fat cells have numerous small peroxisomes, while kidney cells have fewer and larger o...
