Here's why:

* Lysosomes are the "recycling centers" of the cell. Their primary function is to break down waste products, worn-out organelles, and ingested material. They contain powerful digestive enzymes that can break down various molecules.

* Cellular respiration occurs in mitochondria. These organelles are responsible for generating energy (ATP) through the breakdown of glucose in the presence of oxygen.

Therefore, lysosomes and mitochondria have distinct roles in the cell. While lysosomes break down cellular waste, mitochondria are the powerhouses of the cell, generating energy for its various functions.
