Meaning of Peroxisome

What is Peroxisome:

Peroxisome is a organelle present in cells eukaryotes (with defined cell nucleus) that float in the cytosol and meet metabolic functions such as oxidation and removal of hydrogen peroxide (HtwoEITHERtwo).

Peroxisomes form from the smooth endoplasmic reticulum and in mitochondria (animal cells only) and were first discovered by cytologist and biochemist Christian de Duve (1917-2013), along with lysosomes.

They are called peroxisomes because the first enzymes found in their structure were peroxidases. They are found in the cytosol and are called organelles because they are compartments with specialized functions.

Peroxisome characteristics

Peroxisomes are characterized by their ability to change size and form new peroxisomes by division.

Peroxisomes change enzymes to fulfill the necessary metabolic functions of each cell depending on the function of the cell, the most common being urate oxidase and catalase. About 50 different types of enzymes have been identified.

In addition, the peroxisome is distributed into the cytoplasm via the microtubules of the cell’s cytoskeleton and matures to incorporate proteins synthesized by ribosomes.

peroxisome in animal cell

Peroxisomes in animal cells are formed in both the smooth endoplasmic reticulum and mitochondria. Some of the metabolic functions of peroxisomes include lipid metabolism and protection of cells against oxidation.

peroxisome in plant cell

Peroxisomes in plant cells and fungi are exclusive organelles for the process called ß-oxidation, where carbon dioxide (CO) residues are oxidized.two) for photorespiration.

In this sense, photorespiration is the use of oxygen (Otwo) and the release of carbon dioxide (COtwo).

peroxisome and lysosome

The peroxisome and the lysosome were both discovered by Christian de Duve in 1965 and both are found in the cytosol.

The peroxisome carries out the chemical reactions necessary for oxidation and the production of hydrogen peroxide (HtwoEITHERtwo).

On the other hand, lysosomes are considered the recycling center of the cell, maintaining the acidic PH for the decomposition of cellular waste.

peroxisome and glyoxysomes

Glyoxysomes are called peroxisomes that are present in the seeds and store reserve substances. These glyoxysomes will transform fatty acids into sugar during germination.
