lysosomeMembrane-enclosed organelle found in all eukaryotic cells (see eukaryote) that is responsible for the cell's digestion of macromolecules, old cell parts, and microorganisms. Lysosomes contain a wide variety of enzymes that break down macromolecules such as nucleic acids, proteins, and polysaccharides. Many of the products of lysosomal digestion, including amino acids and nucleotides, are recycled back to the cell for use in synthesizing new cellular components. |

Hemocytic lysosome response in the snail Helix aspersa after exposure to the fungicide copper oxychloride. The researchers posit that nerve cells hungry for choline compounds raid their own cell membranes for phosphatidylcholine; this leaves holes on the underside of the membrane and possibly exposes portions of APP to marauding lysosomes. Given that during synthesis of the C/Fe particulates, the material is subjected to extreme acidification procedures, the acidification reached in a lysosome would not be sufficient to decompose the particle. |
