A hormone secreted by beta cells of the pancreas in response to increased blood levels of glucose. Assists in maintaining blood glucose by increasing the movement of proteins from inside the cell to the cell membrane which allow glucose to enter the cell. Insulin also stimulate liver and muscles to take up glucose and store it as glycogen. A hormone secreted by the pancreas in response to decreased blood levels of glucose. Acts in an opposite way to insulin. It causes the liver to convert its stored glycogen into glucose which is secreted into the bloodstream and transported to the cells for energy.
