In this cell biology lecture, Professor Zach Murphy delivers a focused and high-yield overview of Lysosomes, highlighting their structure, function, and clinical relevance. As the primary degradative organelles of the cell, lysosomes play a critical role in breaking down macromolecules and maintaining cellular homeostasis.

We explore how lysosomes form from the Golgi apparatus, the importance of their acidic environment, and the role of acid hydrolases in digesting proteins, lipids, nucleic acids, and carbohydrates. You’ll also learn how these organelles are involved in autophagy, endocytosis, and phagocytosis, recycling cellular components and eliminating pathogens.

The lecture ties in major lysosomal storage disorders, including Tay-Sachs, Gaucher, and Niemann-Pick disease, showing how enzyme deficiencies disrupt lysosomal function and lead to disease.
