Apr 28, 2017 · Functions of the Lysosome. Lysosomes digest many complex molecules such as carbohydrates, lipids, proteins, and nucleic acids, which the cell then recycles for other uses. The pH of lysosomes is acidic (around pH 5) because their hydrolytic enzymes function best at this pH instead of at the neutral pH of the rest of the cell.
The main function of lysosomes is to breakdown and recycle cellular debris, discarded cellular contents and foreign pathogens, however, the digestive enzymes may end up bursting from the lysosome, damaging the cell themselves, and this can cause the cell to die.

Function and structure Lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides , nucleic acids , carbohydrates , and lipids ( lysosomal lipase ).
Apr 13, 2024 · lysosome, subcellular organelle that is found in nearly all types of eukaryotic cells (cells with a clearly defined nucleus) and that is responsible for the digestion of macromolecules, old cell parts, and microorganisms. Each lysosome is surrounded by a membrane that maintains an acidic environment within the interior via a proton pump.

May 18, 2023 · Lysosomes are responsible for three main functions: 1. Digestion of Macromolecules. One of the significant purposes of the lysosome is the digestion of foreign molecules taken up inside the cell by endocytosis. Lysosomes contain about 50 hydrolyzing enzymes that digest macromolecules (nucleic acid, proteins, carbohydrates, and lipids) by ...
Oct 31, 2023 · 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.
