Web8 iun. 2024 · A lysosome has three main functions: the breakdown/digestion of macromolecules (carbohydrates, lipids, proteins, and nucleic acids), cell membrane repairs, and responses against foreign substances such as bacteria, viruses and other antigens. Webd. Lysosomes are larger, membrane-bound organelles while proteasomes are free floating protein complexes. So, lysosomes cannot break down proteins in the nucleus because it cannot enter it due to its size, but proteasomes can. Lysosomes can degrade proteins, lipids, DNA, and sugar, while proteasomes can only degrade proteins.
