8. large subunit small subunit Protein channel Lipid bilayer CO2 H2O The Pancreas is signaled to make insulin Cells in the body are signaled to take up glucose When blood sugar gets to ↓ the brain sends the pancreas a signal to make Glucagon(protein) After you eat a meal, Blood Sugar is ↑ The liver is signaled to store any extra glucose as Glycogen This causes the blood glucose to rise, or if you haven’t ate in a while and there is no more glycogen to break down you start to feel hungry The body uses glucose to make ATP and power cells. The more active you are the more glucose your body needs Receptor Proteins in the liver are signaled by the Glucagon to start breaking glycogen down into glucose
