Review What does cAMP activate? T or F? the alpha subunit has to be separated from the beta and gamma? True A receptor has to be activated to activate GDP binding protein. True An activated receptor is a ligand binding to it. When the ligand binds what will happen to the receptor? In all cases the ligand binds it goes through a conformational change. That is the signal to turn it on. Non polar ligands bind to transmembrane proteins? NO What characteristic be of a ligand that binds to a transmembrane? Hydrophilic on it to pass through the membrane A ligand with hydrophilic ligand it would be non polar. A classic non-polar bond is a steroid. Have receptors located. Floating around in the cytoplasm. Signal transaction, nuclear and cytoplasmic Cytoplasmic is rapid Nuclear is quick(slower than cytoplasmic but quick)
