The beta cells of the pancreas produce insulin and alpha produce glucagon. When there is a rise in blood sugar level the beta cells secrete insulin, which stimulates cells in the body to grab glucose, leading to a fall in glucose levels. It also instructs the liver to store glucose as glycogen (glucose reserve). When glucose levels fall below a set point or optimal level, the alpha cells secrete glucagons, which instruct the liver to convert glycogen back to glucose. These two pancreatic hormones are responsible for maintaining healthy blood glucose levels.
