13) Unit 1 - Coordination Flashcards
How to multicellular organisms achieve co-ordination
through extracellular signalling molecules, receptors and responses
what is a receptor protein
a protein with a binding site for a signal molecule
What happens when a signal molecule binds to a receptor protein
Produces a change of conformation which alters the response of the cell
Different cell types can produce specific _________ which can only be detected and responded to by cells with the specific ___________
Different cell types produce specific SIGNALS which can only be detected and responded to by cells with the specific RECEPTOR
different cells may show different _________ to the same signal (i.e tissue specific)
