Membrane transport

The video tutorial by Dr. Morton covers the permeability of the cell membrane, focusing on the concentration of ions like sodium and potassium. It explains diffusion, including simple and facilitated diffusion, and the role of membrane proteins in these processes. The tutorial also discusses osmosis and active transport, highlighting primary and secondary active transport mechanisms, such as the sodium-potassium pump. The content is designed to help students understand how substances move across cell membranes and the physiological significance of these processes.
