In this video that covers section 2.7 of the AP Biology curriculum - Facilitated Diffusion - we’ll take a close look at many aspects of this passive form of membrane transport. We’ll start by reviewing the differences between active transport and passive transport. Then, we’ll move on to discover the differences between carrier proteins, ion channels, and aquaporins. We’ll see how aquaporins actively select for water molecules and how different types of ion channels can be voltage-gated, ligand-gated, or mechanically-gated. Lastly, we’ll take a look at how active transport creates ion gradients that can be coupled with modes of facilitated diffusion to complete important cellular processes such as sending nerve signals and creating ATP!
