Break down various biomolecules it engulfs
- 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). The enzymes responsible for this hydrolysis require an acidic environment for optimal activity.

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.

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.
One of the major functions of lysosomes is the digestion of material taken up from outside the cell by endocytosis, which is discussed in detail in Chapter 12. However, the role of lysosomes in the digestion of material taken up by endocytosis relates not only to the function of lysosomes but also to their formation.
May 4, 2020 · Abstract. Lysosomes are the main proteolytic compartments of mammalian cells comprising of a battery of hydrolases. Lysosomes dispose and recycle extracellular or intracellular macromolecules by fusing with endosomes or autophagosomes through specific waste clearance processes such as chaperone-mediated autophagy or microautophagy.
