Answer:
protein hormone that tells animal cells to store blood glucose as glycogen is Insulin.
Step-by-step explanation:
Insulin is a peptide hormone,secreted from the beta cell illets of langerhans of pancreas and then binds to the surface receptor of the target cell.
Insulin play an important role in the maintainance of blood glucose level, basically it helps to decrease the blood sugar level by activating the metabolic pathways that deals with the utilization of glucose such as glycogenesis or synthesis of glycogen from glucose.
Thus the extra blood glucose is stored in form of glycogen in both liver and muscle.
