			Biomembranes II: 
			Membrane Dynamics and Communication 
			Concept 2: Endocytosis and 
			Exocytosis 
			 
			Endocytosis is the movement of materials into a cell via 
			membranous vesicles. Exocytosis is the movement of materials out of 
			a cell via membranous vesicles. 
			 
			
			  
			These processes allow patches of 
			membrane to flow from compartment to compartment, and require us to 
			think of a cell as a dynamic, rather than static, structure.
