Insulin and glucagon hormones are responsible for controlling the sugar and glucose levels in the human body.
Glucagon and Insulin are needed to monitor and regulate the concentrations of blood glucose. A group of pancreatic cells called islets of Langerhans secrets these two hormones. The alpha cells of the islets of Langerhans helps in increasing the blood glucose level by secreting glucagon hormone while the beta cells release insulin which helps in lowering down the blood glucose level.
