| Description | What initiates the break down of glycogen in liver cells? During times of starvation, when the blood glucose levels are low, the alpha cells of the pancreas release a peptide hormone called glucagon. Glucagon binds to seven transmembrane receptors found on liver cells, which in turns initiates a signal transduction pathway that ultimately leads to the break down of glycogen into glucose. In addition, epinephrine, a tyrosine-based hormone released by the adrenal medulla, binds to the alpha-adrenergic receptor and initiates the phosphoinositide cascade. This releases calcium ions into the cytoplasm from the endoplasmic reticulum, which helps initiate glycogen breakdown. |
