How lysosomes help clean up dead organelles and intruders like viruses?

Lysosomes are membrane-bound organelles that contain digestive enzymes capable of breaking down various biological molecules. They help clean up dead organelles through a process called autophagy, where damaged or obsolete cellular components are engulfed and degraded. Additionally, lysosomes can digest intruders like viruses by fusing with phagosomes, which contain the engulfed pathogens, thereby breaking them down into harmless components. This cleanup process is essential for maintaining cellular health and function.
