In this video, Cellular Membranes: Moving material and information across the membranes - membrane transport, I look at how the cell resolves the issue of membranes preventing ions, molecules and information from entering or leaving the cell. That is, how do we transport such things across the membrane?
In this video, I examine cellular transport and how proteins facilitate the crucial exchange of molecules, ions, and information across cell membranes. The video explains both passive and active transport mechanisms and highlights the specialised roles of carrier and channel proteins in these processes.
This is one of four videos on membranes, the other two being:
- Cellular Membranes: Protection, Structure, and Function
- Cellular Membranes: The role of proteins in the membranes
- Cellular Membranes: Moving material and information across the membranes - membrane transport
- Cellular Membranes: Moving information across the membrane - the receptors
