With type 2 diabetes, your body makes insulin but your cells dont respond to it normally. In the liver, glucose can be converted into glycogen or It is a large multi-branched polymer of glucose which is accumulated in response to insulin and broken down into glucose in response to glucagon. Biology Notes IGCSE Cambridge 2014 | PDF | Osmosis | Enzyme Insulin helps cells absorb glucose in your bloodstream so the levels of glucose don't get too .

Insulin and glucagon are hormones that help to regulate blood sugar levels. From this the body will then respond to produce more . But it normally degrades very quickly. BBC Bitesize. If the blood glucose level falls to dangerously low levels (as during very heavy exercise or lack of food for extended periods), the alpha cells of the pancreas release glucagon, a hormone which travels through the blood to the liver, where it binds to glucagon receptors on the surface of liver cells and stimulates them to break down glycogen stored inside the cells into glucose (this process is called glycogenolysis). The whole process ensures that your body gets enough energy. If the blood glucose concentration is too high, the pancreas produces insulin. People with type 1 diabetes need to take insulin regularly, but glucagon is usually only for emergencies. To help you revise we've created this quiz for AQA's Unit 3.
