BIO101: Introduction to Molecular and Cellular Biology

Watch this lecture that reviews cell membranes and details their central role in cell function and survival. Learn the components on the plasma membrane and reflect on their macromolecule characteristics.

After you have watched the videos in this section, you should be able to explain how molecules cross cell membranes, discuss the channel proteins, carrier proteins, pumps, and aquaporins involved in transport, distinguish between osmosis, facilitated diffusion, and active transport, and describe how large molecules are transported across a cell membrane.
