Lysosomes contains Hydrolytic enzymes (Digestive enzymes) . This enzymes helps to digest intra & extracellular substances.

Main Function of Lysosome:
Lysosomes are membrane-bound organelles found in animal cells that contain digestive enzymes. They play a crucial role in intracellular digestion and the recycling of cellular components.
Key Functions of Lysosomes:
1. Intracellular Digestion: Lysosomes are responsible for the breakdown of various biomolecules, including proteins, carbohydrates, lipids, and nucleic acids. They contain hydrolytic enzymes, such as proteases, lipases, carbohydrases, and nucleases, which break down these molecules into smaller components that can be utilized by the cell.
2. Extracellular Digestion: In some cases, lysosomes fuse with phagosomes or endosomes to carry out extracellular digestion. This occurs mainly in specialized cells, such as macrophages, which engulf and digest foreign particles, pathogens, or cellular debris through a process called phagocytosis.
3. Cellular Waste Recycling: Lysosomes also play a vital role in autophagy, a process by which damaged or obsolete cellular components are engulfed by lysosomes and degraded. This recycling process helps maintain cellular homeostasis by removing unwanted or malfunctioning organelles and recycling their components for reuse.
4. Programmed Cell Death: Lysosomes are involved in a type of programmed cell death called apoptosis. During apoptosis, lysosomes release their hydrolytic enzymes into the cytoplasm, leading to the breakdown of cellular components and eventual cell death.
5. Defense against Pathogens: Lysosomes participate in the immune response by aiding in the degradation of engulfed pathogens, such as bacteria or viruses, within phagosomes.
In conclusion, the main function of lysosomes is intracellular digestion, extracellular digestion in specialized cells, cellular waste recycling, programmed cell death, and defense against pathogens.
