The _____ are involved in the digestion of substances that are no longer needed by the cell.

The lysosomes are involved in the digestion of substances that are no longer needed by the cell. They are membrane-bound organelles that contain digestive enzymes capable of breaking down a variety of biomolecules, including proteins, nucleic acids, lipids, and carbohydrates. Lysosomes play a crucial role in the cell's waste disposal system, allowing for the degradation of cellular debris, obsolete organelles, and engulfed pathogens.

When a cell is damaged or when it needs to eliminate waste, lysosomes come into action by fusing with vacuoles that contain the material to be digested. The digestive enzymes within lysosomes catalyze the breakdown of these materials into their basic components, which can then be recycled or expelled from the cell. This process not only helps maintain cellular health but also supports essential functions like cellular repair and nutrient recycling. Their malfunction can lead to various diseases, including storage disorders and other metabolic issues, highlighting their importance in cellular maintenance.
