Document Summary
Cells require a continuous supply of nutrients, and the management of nutrients is under endocrine control. Insulin and glucagon produced in pancreas of islets of langerhans. During digestion stimulate beta cells to produce insulin. Stomach and intestines break down large macromolecules: release of glucose stimulate beta cells to produce insulin, gastrin hormone produced in the stomach also activates beta cells. Combination and each of these stimulate beta cells. Facors storage of carbs, amino acids, fatty acids from: fat or adipose tissue, bind to insuling receptors and begin series of signal transduction events that lead to glucose transporters. Insulin binds to receptors on muscle fiber and initiate a signal cascade. Allos cells to take up glucose through facilitated diffusion. Insulin also stimulates target cells that synthesize: hypoglycemic affect, glycogen storage, takes the small subunits and build them up, triglycerides, short chain fatty acids, proteins from glucose, fatty acids, aas.
