what will happen if the concentration of glucose in the blood decreases/increases too far from a certain level
cell function will be disrupted
the control of blood glucose is a key part of
homeostasis
blood glucose concentration is controlled by
two hormones secreted by endocrine tissue in the pancreas
which cells is the tissue of the pancreas made up of
islets of Langerhans
what are the two cell types of the islets of Langerhans
αlpha cells and βeta cells
what do the alpha cells of the islets of Langerhans secrete
the hormone glucagon
what do the beta cells of the islets of Langerhans secrete
insulin
what is the function of the alpha and beta cells of the islets of Langerhans
to act as receptors and initiate the response for controlling blood glucose concentration
what can the control of blood glucose by glucagon demonstrate
the principles of cell signalling
