2.4 Plasma Membranes - AP Biology

In this video, I describe the composition, structure and function of the phospholipid bilayer, especially how the amphipathic characteristics of phospholipids contribute to the selective permeability of the plasma membrane.

ENE-2.A: Describe the roles of each of the components of the cell membrane in maintaining the internal environment of the cell.
ENE-2.B: Describe the Fluid Mosaic Model of Cell Membranes.

i just have to drop a thank you note really quick Ive never taken bio so I watch your videos before we start the unit and take notes and I actually did well on my first test. Your videos make it easy to understand AP Biology without much background knowledge. Thank you for making them!

Hi Mr Poser,
