In this video, Cellular Membranes: Moving information across the membrane - the receptors, I discuss one of my favourite areas of cell biology - cell signalling.
In the video, I look at how cells receive information across their membranes and the three primary methods they use to sense external molecules and ions, from diffusion through the membrane to communication via gap junctions and interactions with specialised proteins called receptors.
The video covers various receptor types, including ion-channel linked receptors, G-protein-coupled receptors (GPCRs), and enzyme-linked receptors, explaining how each type facilitates the transmission of signals inside the cell.
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
