Give one example of a ligand-receptor pair for each of the six generic types of cell signaling. Do not include the details of the pathway, just give its name and how/why it is important to the cell. Line up the six generic types, using the generix names, according to soeed of the signaling process and give an explanation of the order that you determined. I'm guessing the six types are: GCPR Receptor Tyrosine Kinase Receptor Guanylyl Cyclase Adhesion receptor (integrin)...

Signaling of GPCRs (G-protein coupled receptors) is terminated by which mechanism? Phosphorylation of receptors by cAMP (cyclic adenosine monophosphate) activated PKA (protein kinase A), which blocks the interaction with G-protein Cleavage of the GPCRs by receptor-specific serine or threonine proteases Hydrolysis of GTP (guanosine triphosphate) to GDP (guonosine diphosphate) by G-protein α. None of the above All of the above
