A lipid-soluble hormone diffuses across the plasma membrane and binds to a receptor. 2.The hormone-receptor complex binds to DNA in the nucleus and causes transcription. WebBIO ch 7. Epinephrine stimulates a G protein-mediated cascade within liver cells, resulting in phosphorylation of two enzymes: glycogen synthase, which is _______, and glycogen phosphorylase, which is _______. This results in more glucose being released to the blood and less glycogen being stored.
