Introduction:
The lysosome is a membrane-bound organelle found in eukaryotic cells that serves as the cell's waste disposal system. It contains digestive enzymes that break down various types of biomolecules.

Lysosome Structure:
Lysosomes are spherical organelles that are surrounded by a single membrane. They contain hydrolytic enzymes that are capable of breaking down proteins, lipids, carbohydrates, and nucleic acids.

Lysosome Function:
The primary function of lysosomes is to break down and recycle cellular waste materials. They are responsible for the degradation of various types of biomolecules, including damaged organelles, foreign substances, and cellular debris.

Autophagy:
Autophagy is a process by which lysosomes break down and recycle damaged or dysfunctional organelles. This process helps to maintain cellular homeostasis and prevent the accumulation of toxic materials within the cell.

Phagocytosis:
Phagocytosis is a process by which lysosomes break down and digest foreign substances that have been taken up by the cell. This process is important for the immune system, as it allows cells to destroy invading pathogens.

Diseases Associated with Lysosome Dysfunction:
Lysosome dysfunction can lead to a number of diseases, including lysosomal storage diseases and neurodegenerative disorders such as Alzheimer's and Parkinson's disease.

Conclusion:
In summary, lysosomes are the waste disposal system of a cell. They are responsible for breaking down and recycling cellular waste materials through processes such as autophagy and phagocytosis. Dysfunction of lysosomes can lead to a number of diseases, highlighting the importance of these organelles for cellular homeostasis.

Lysosomes are membrane-bounded organelle which acts as waste disposal system of a cell. They help to keep the cell clean by digesting any foreign material or worn out cells. ... When the cell membrane get ruptured and the cellular environment gets change, lysosomes may burst and the enzymes digest their own cell.
