What is the role of lysosomes in the cell?

Energy production
Hydrolytic breakdown of waste materials
Protein synthesis
Photosynthesis

The correct answer is: Hydrolytic breakdown of waste materials

Lysosomes play a crucial role in the cell by being the primary site for the hydrolytic breakdown of waste materials and macromolecules. They contain a variety of hydrolytic enzymes that are capable of digesting lipids, proteins, and carbohydrates. This digestive process helps to recycle cellular components and remove damaged organelles or pathogens, thereby maintaining cellular health and homeostasis. By functioning as the cell's waste disposal system, lysosomes ensure that materials no longer needed by the cell are effectively broken down and either recycled for new cellular components or expelled from the cell. This activity is vital for cellular functioning and survival, particularly under stress conditions or when cells are undergoing normal turnover.
