This free course, Cell signalling, explains the general principles of signal transduction and specifically, how even the simplest organisms can detect and respond to events in their ever-changing environment.
Course learning outcomes
After studying this course, you should be able to:
define and use each of the terms printed in bold in the text
understand the basic principles of signal transduction mechanisms, in particular the concepts of response specificity, signal amplitude and duration, signal integration and intracellular location

describe the mechanisms by which different receptors may be activated by their respective ligands
describe and give examples of the structure and properties of the major components of signal transduction pathways.
