Endosome vs. Lysosome: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 20, 2024
Endosomes are membrane-bound vesicles for sorting cell material, while lysosomes are organelles that break down waste using enzymes.

Key Differences

Endosomes are involved in the sorting and transportation of cellular materials, playing a crucial role in endocytosis. Lysosomes, conversely, are responsible for the degradation of cellular waste and foreign particles.

Endosomes are formed from the inward budding of the plasma membrane, creating a diverse range of vesicle types. Lysosomes originate from the Golgi apparatus and are characterized by their acidic environment.

Endosomes primarily contain sorting and transport proteins, while lysosomes are filled with hydrolytic enzymes essential for breaking down various biomolecules.

Endosomes have a variable pH environment, gradually becoming more acidic, which is crucial for their sorting function. Lysosomes maintain a consistently acidic pH, which is optimal for the activity of their digestive enzymes.

Endosomes interact extensively with the cell's transport system, including the trans-Golgi network and plasma membrane. Lysosomes, meanwhile, often fuse with autophagosomes to facilitate the breakdown of cellular components.
