To help you revise we've created this quiz for AQA's Unit 3. When blood sugar levels drop, glucagon instructs the liver to convert the glycogen back to glucose, causing a persons blood sugar levels to return to normal. If blood sugar levels are low, glucagon tells your body to break down glycogen (stored glucose) in the liver to release glucose and increase glucose levels. Both types of diabetes, if untreated, result in too much glucose remaining in the blood (hyperglycemia) and many of the same complications. 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. Proteins must therefore by hydrolyzed within muscle to produce Hormones are released into the bloodstream by groups of cells called endocrine glands . A person with diabetes cannot regulate their blood sugar, mainly because the pancreas does not release enough insulin. Insulin lowers your blood sugar levels, and glucagon raises them. Furthermore, insulin and glucagon have various physiologic roles in addition to the regulation of carbohydrate metabolism.
