Peroxisomes are enclosed by how many membranes, and carry out which reactions?

1. Peroxisomes are small, round organelles enclosed by single membranes. 2. They carry out oxidation reactions that break down fatty acids and amino acids. 3. They also detoxify many poisons that may enter the body, and alcohol is detoxified by peroxisomes in liver cells. 4. Double membranes belong to mitochondria, chloroplasts and the nuclear envelope, not to peroxisomes. 5. One membrane and oxidation reactions is the correct pairing. 6. Hydrolysis is the lysosome's chemistry, so pairing it with a peroxisome gets both the membrane count and the reaction wrong. _Source: OpenStax Biology (1st ed., CC BY 4.0), Ch 4 "Cell Structure", section 4.3 Eukaryotic Cells_
