Peroxisomes in Eukaryotic Cells

They are organelles found in eukaryotic cells-plant and animal. They collect toxic peroxides which are by products of cellular chemical reactions. Perosides are broken down inside the peroxisome by enzyme catalase. Enzymes that break down the toxic hydrogen peroxide are transported into the peroxisomes by the ______ after they are synthesized by free ribosomes.

The organ that peroxisomes are most abundant in is the ______.

Each ______ has a single membrane. Each cell contains several hundred peroxisomes. They resemble a lysosome but are not the same. Size is variable, but it is roughly about 700nm. A peroxisome is found in the cytoplasm of a cell.
