Can you give examples of each? o Name one membrane bound impermeable signal. o Name one soluble, secreted membrane impermeable protein signal. o Name a non-proteinaceous signal Where do proteinaceous signals come from? Where do they cross the membrane? What types of proteins are they? What is the difference between a soluble protein ligand (like EGF) and a related membrane-bound one (like Boss)? Explain the 2 mechanisms to activate a steroid hormone receptor. Name and differentiate between the 3 types of receptors for membrane impermeable signals. o ion channel receptor o G protein coupled receptor name a couple of effectors that are regulated by a trimeric Gprotein coupled receptors o enzyme linked receptor name a few enzymatic activities that might be found in an enzyme linked receptor UNDERSTAND how a trimeric G protein cycles between the activated and
