This MCAT Basics podcast covers biological membranes. First, the podcast introduces a few topics regarding membranes: what they are, how they are formed, their presence in the cell, and cell-to-cell junctions. Second, it addresses transport through the membrane, including simple diffusion, active vs. passive transport, and transport membrane proteins. Next, the discussion moves to membrane proteins, including receptors, transporters, and the differences between integral, peripheral, and lipid-anchored proteins. Finally, the podcast covers membrane dynamics, such as endocytosis and the transmembrane system, and discusses membrane potential.
