Molecule Signal Transduction Pathways Diagram Poster

Signal transduction is the process by which an extracellular signalling molecule activates a membrane receptor, that in turn alters intracellular molecules creating a response. There are two stages in this process: a signalling molecule activates a certain receptor on the cell membrane, causing a second messenger to continue the signal into the cell and elicit a physiological response. In either step, the signal can be amplified, meaning that one signalling molecule can cause many responses. Image reproduction rights can be found in the link near the bottom of this description.
