blood gulcose
glucose uptake pathway
2.) once the insulin is bound, phosphate groups are added to the receptor in process called autophosphorylation
3.) the autophosphorylation of the receptor begins a signal cascade, in which several other proteins are phosphorylated in sequence. each can activate many other proteins
1.) two molecules of insulin must bind to the extracellular domain of the insulin receptor to activate it
4.) the cascade sequence results in the activation of many Glut4 secretory vesicles, which produce the Glut4 glucose transporters.

the endocrine portion of the pancreas produces two hormones, insulin and glucagon, which maintain blood glucose at a steady state through negtive feed back
blood glucose levels are controlled by negative feedback involving two hormones,insulin and glucagon
insulin lowers blood glucose by promoting the uptake of glucose by the bodys cells and the conversion of glucose into the storage molecule glycogen in the liver.
glucose increases blood glucose by stimulating the breakdown of stored glycogen and the synthesis of glucose from amino acids
