1. Membrane-bound organelles found in eukaryotic cells that break down fatty acids and detoxify harmful substances, producing and decomposing hydrogen peroxide.
Usage: biology; plural form of peroxisome; typically used in scientific and educational contexts

Examples

• Peroxisomes play a crucial role in cellular metabolism by breaking down fatty acids.
• The enzyme catalase in peroxisomes breaks down hydrogen peroxide into water and oxygen.
• Defects in peroxisome function can lead to serious genetic disorders.
• Plant cells contain peroxisomes that are involved in photorespiration.
• Scientists study peroxisomes to understand how cells manage oxidative stress.
