Cell Membrane Transport. Simple & Facilitated Diffusion. Primary vs Secondary Active Transport.

This lecture starts by defining passive transport and then explains the difference between simple diffusion, diffusion through channels, and facilitated diffusion. Next it defines active transport and then explains the difference between primary and secondary active transport. It finishes by differentiating between antiport and symport.
