Learn about how cells sense and respond to extrinsic stimuli, a capacity that allows them to communicate with each other and to respond to changes in their environment. This free course, General principles of cellular communication, explains cell signalling pathways in general terms and identifies some of the universal characteristics of signalling pathway components.
Course learning outcomes
After studying this course, you should be able to:
describe in general terms how extrinsic signals activate cell signalling pathways to elicit cellular responses
describe how cell signalling processes facilitate quorum sensing in bacteria
outline the diverse roles played by proteins in cellular communication and how various proteins can function together in a signalling pathway
relate the activities and properties (including domain structure) of proteins to their roles in signalling.
