  • Peroxisome
    Organelle compartmentalizing toxic reactions, notably hydrogen peroxide production and detoxification, and involved in lipid metabolism.
  • Hydrogen Peroxide
    Reactive molecule generated during oxidation reactions, confined within a specific organelle to prevent cellular damage.
  • Catalase
    Enzyme that converts hydrogen peroxide into water and oxygen, protecting cells from oxidative damage.
  • Lipid Synthesis
    Process occurring in certain organelles, producing specialized phospholipids essential for cell membranes.
  • Plasmagen
    Phospholipid with a unique ether bond, synthesized in a specific organelle, important for membrane structure.
  • β-Oxidation
    Metabolic pathway breaking down fatty acids within a specialized organelle, contributing to energy production.
  • Sorting Signal
    Short amino acid sequence, such as SKL, directing proteins to their correct organelle destination.
  • Peroxin
    Protein facilitating import of other proteins into a specific organelle, ensuring proper function.
  • Endoplasmic Reticulum
    Organelle from which peroxisomes originate, providing membrane material for their formation.
  • Vesicle
    Small membrane-bound structure that buds from the ER and fuses to form larger organelles.
  • Zellweger Syndrome
    Genetic disorder caused by defects in peroxisomal proteins, leading to severe developmental issues.
  • Detoxification
    Cellular process neutralizing harmful molecules, often involving specialized organelles and enzymes.
  • Phospholipid
    Major membrane component, sometimes synthesized with unique bonds in specialized organelles.
