Peroxisomes

Kyle, colby

What are peroxisomes?

Peroxisomes are microbodies. They are bound by a single membrane and contain enzymes that produce hydrogen peroxide as a by-product.

How Does It Works?

Peroxisomes contain enzymes that work by transferring hydrogen from a substrate to oxygen, thereby producing hydrogen peroxide as a by-product. Hydrogen peroxide is toxic to the cell, but peroxisomes also contain an enzyme that is capable of converting hydrogen peroxide to water.

Some functions of peroxisomes include detoxifying alcohol, bile acid formation, and using oxygen to break down fats. Similar to lysosomes, peroxisomes are excellent examples of compartmentalized structure relating to cellular function.
