Regulation of blood glucose

HideShow resource information

IF BLOOD GLUCOSE RISES TOO HIGH                                                                         

1. The stimulus - a rise in blood glucose e.g just eaten something

2. Receptors - Beta cells in the islets of Langerhans in the pancreas detect the rise in blood glucose levels

3. Insulin is secreted into the blood

4. Response - The target cells are the hepatocytes (liver cells). The molecules of insulin complementary bind to receptors on the hepatocytes.The effects of this are:

  • Hepatocytes take up more glucose
  • More glucose channel proteins are inserted in the cell membrane for facilitated diffusion
  • Glucose is converted…
