are slower, but longer acting than the nervous system. 4.5.3.2 4.5.3.2 Control of blood glucose concentration Blood glucose concentration is monitored and controlled by the pancreas. It produces insulin, which causes glucose from the blood to enter cells. Glucose is converted to glycogen in liver and muscle cells for storage. HT: Glucagon is also produced by the pancreas to convert stored glycogen back into Describe how blood glucose concentration is monitored and controlled. Explain when insulin is produced and how it helps to control blood glucose levels. Describe glycogen as a stored carbohydrate. HT: Explain when glucagon is produced by the pancreas and its effect on blood glucose levels. Explain how insulin and glucagon work together to control blood glucose levels. Explain the cause, effects, treatment and problems associated with Type 1 diabetes. 1 Class practical – investigating sugar levels in urine. What disease can cause glucose in urine?
