What is the primary function of lysosomes?

Lysosomes are often referred to as the "digestive system" of the cell due to their primary function of breaking down waste materials and cellular debris. They contain a variety of enzymes that can digest different types of biomolecules, including proteins, lipids, carbohydrates, and nucleic acids. This process is crucial for maintaining cellular health, as it allows the cell to recycle components, remove damaged organelles, and clear away foreign invaders. The activity within lysosomes helps prevent the accumulation of waste that could be toxic to the cell, thereby supporting cellular function and overall homeostasis.
