	1) Respiratory Epithelial cells- Thin Section - See Golgi and secretory granules (SG); Dark spots are lysosomes stained with acid phosphatase
	2) Purified Lysosomes
	3) Shows the formation of coated pits. a) Density on the external portion - ligand receptor b) Density on the outside is the clathrin
	4) Isolated clathrin = Structure composed of hexigons and pentagons
	5) Cell Starvation - C) 4 Membranes = Mitochondria surrounded by smooth ER D) Mitochondria gets degraded to form a multivasicular structure
	6) Neruon from cerebellum of a child with Tay Sachs
