11.In response to a hormone the receptors increase their sensitivity. This is an example of regulation 12 Lipid soluble homones bind with a receptors. 13. Messenger RNA is synthesized whena soluble hormone binds with a 14.G protein is comprised of 15.Alpha subunit of G protein becomes active when it picks up 16.lf alpha subunit becomes active and opens Ca+ channels ther receptor subunits is the second messenger 17.lf alpha subunit becomes active and activates guanylyl cyclase then is the second messenger 18.T/F IP3 and DAG are second messengers produced if adenyl cyclase becomes activated 19.T/F Intracellular enzymes can never be activated if G-protein is not involved. 20.Insulin acts on cells by directly adding a phosphate to intracellular proteins/enzymes 21 receptors are best suited for mediating ar long time.
