Is a peroxisome an organelle
WebCentrioles are paired barrel-shaped organelles (centrosomes) located in the cytoplasm of animal cells near the nuclear envelope. All animal cells have centrioles, whereas only some lower plant forms have centrioles in their cells (e.g., the male gametes of charophytes, bryophytes, seedless vascular plants, cycads, and ginkgo). WebThe peroxisome is a single membrane-enclosed organelle that plays an important role in metabolism. The main metabolic functions of peroxisomes in mammalian cells include β-oxidation of very long chain fatty acids, α-oxidation of branched chain fatty acids, synthesis of bile acids and ether-linked phospholipids, and removal of reactive oxygen species.

A peroxisome (IPA: [pɛɜˈɹɒksɪˌsoʊm]) is a membrane-bound organelle, a type of microbody, found in the cytoplasm of virtually all eukaryotic cells. Peroxisomes are oxidative organelles. Frequently, molecular oxygen serves as a co-substrate, from which hydrogen peroxide (H2O2) is then formed. Peroxisomes owe their name to hydrogen peroxide generating and scavenging activities. T…
