Peroxisomes are membrane-bound organelles responsible for oxidative metabolic processes, including β-oxidation of very long-chain fatty acids (VLCFAs, typically ≥ C22). While mitochondria (Option A) perform β-oxidation of short- and medium-chain fatty acids, peroxisomes handle VLCFAs that mitochondria cannot directly process. Enzymes in peroxisomes initiate chain shortening, and the shortened fatty acids are then shuttled to mitochondria for further oxidation. Lysosomes (Option C) function mainly in degradation of macromolecules through acid hydrolases and do not perform fatty acid oxidation. The Golgi apparatus (Option D) modifies, packages, and distributes proteins and lipids but has no role in fatty acid catabolism. This question targets DAT biology’s emphasis on organelle function and metabolic specialization. Knowing peroxisomal disorders (e.g., Zellweger syndrome) can help reinforce the concept, but for the DAT, remember: peroxisomes = VLCFA oxidation and detoxification of hydrogen peroxide.
