when these conditions deviate from their optimal state. These automatic control systems may involve nervous responses or chemical responses. Many of the processes are coordinated by hormones. 4.3.1.5 Blood glucose concentration is monitored and controlled by the pancreas. If the blood glucose concentration is too high, the pancreas produces the hormone insulin, which causes glucose to move from the blood into the cells. In liver and muscle cells excess glucose is converted to glycogen for storage. (HT only) If the blood glucose concentration is too low, the pancreas produces glucagon, which causes glycogen to be converted 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 only) Explain when glucagon is produced by the pancreas and its effect on blood glucose levels. 1 What disease can cause glucose in urine?
