🦊 In this GCSE Biology video, we explain how optimal blood glucose levels are maintained through the continuous conversion between glycogen and glucose within the liver and muscles. Insulin and glucagon, hormones produced by the pancreas, play pivotal roles in this process. Insulin is released when blood glucose levels are high, converting glucose into glycogen to lower blood sugar. Conversely, glucagon is produced when blood glucose levels drop, converting glycogen back into glucose to raise blood sugar levels. This cyclic process exemplifies homeostasis, ensuring stable internal conditions despite external changes.
