Where is the hormone insulin produced and where does it act?
482972
the hormone insulin is produced by the the beta or B-cells of the Islets of Langerhans in the pancreas.its a hypoglycemic factor which helps in the process of glycogenesis which is a anabolic process of forming glycogen from glucose(sugar) present in the blood.this process occurs in the liver.and this way the glucose level in the blood reduces,hence insulin is called hypoglycemic factor.there is another process called glycogenolysis occuring in the liver which is supported by glucagon,a harmone produced by the alpha or A cells of the islets of langerhans present u know where!in this process,the glycogen in the cells are broken down into glucose,released into the blood.this way the blood glucose level increases.thus glucagon is a hyperglycemic factor.the balanced action of both these hormones, whose production is regulated by somatostatin (delta or D cells of islets of langerhans),maintains the blodd sugar level,homeostatis.got it!

Beta cells are the insulin producing cells of the islets.  Alpha cells produce glucagon, delta cells somatostatin, and PP cells pancreatic peptide.

Genetic Engineering can be used in the production of microbial strains that can synthesise insulin - the protein pancreatic hormone, commonly whose deficient production is the reason for Diabetes. Thus commercial availability of this hormone is made possible. Insulin injections have proved to be a life saver for millions of diabetics worldwide. \n\nFor example, a genetically engineered (transgenic) strain of Escherichia coli (the colon bacterium) is used now for insulin mass production.

No, that answer is completely wrong- I assume you know that, since you are asking about the signal transduction pathway.\nSo, like any receptor, the insulin receptor has an extracellular domain that binds the ligand, in this case insulin. When this occurs, a tyrosine kinase inside the cell is activated, which is part of the insulin receptor itself-this is a typical trophic factor receptor function.  This TK  phosphorylates the insulin receptor substrate (IRS) on a number of different tyrosine residues, thus changing it's morphology.  These phosphorylated tyrosine residues on IRS then chemically interact with Src homology domains (SH2)on a number of other signaling proteins. This then starts the cascade of reactions which activates the PI3 kinase pathway, Grb-2, ERK phosphorylation, etc which ends up activating the GLUT transporter, which binds glucose and translocates it across the membrane.  \nGood luck on your exam

Do NOT use insulin that has been frozen. Some insulins are made to release slowly, others immediately. Once it's been frozen the structure will have been altered. Fast acting insulin may not work or be unpredictable. Those longer acting insulins might be released more rapidly or not at all. Throw it out and get a new vial.

B.\n\nA peptide hormone that is produced by fat cells. It plays a role in body weight regulation by acting on the hypothalamus to suppress appetite and burn fat stored in adipose tissue.

The endocrine system is the collection of organs and tissues that make hormones.  The hormones themselves control many things throughout your body, from development to emotional states to simple digestion.  As chemicals which circulate though your blood, they are considered to be 'fast' signals, though not as fast as nerve signals and the like.  Hormones are also never stored in your body... just made quickly as they're needed and used quickly.

The thyroid is one of the larger endocrine glands in the body. It is located in the neck and produces hormones, principally thyroxine and triiodothyronine, that regulate the rate of metabolism and affect the growth and rate of function of many other systems in the body.

Diabetes occurs when the cells in the pancreas produce lesser amounts of insulin.  Their are several different kinds of diabetes.  Some are associated with age, others reflect upon the varying amounts of insulin produced.   The drugs used to treat this are mainly of sulfa origin and promote insulin production.  The disease is extremly important.  Many strides have been achieved over the years, but pancreas transplant is still in its infancy.

estrogen is a female hormone and insulin a hormone which regulates sugar levels in the body which if it is absent causes diabetes

i believe that the hormone is absicac acid or something like that. I know i spelled it wrong, but google it and see what comes up.

It is excreted. The problem is that in a healthy body a significant amount of glucose id broken down by insulin. When a person has diabetes, no insulin (or an disfunctional type of insulin) is produced, and the glucose is not being broken down.

humans synthesis insulin( beta cells) in the pancreas.Beta cells make up 75% of the working cells of this exocrine gland. insulin is used as a "key" by the body to unlock the cells "door", and allow glycagon to enter, then the cell uses the new energy to function. in diabetes, the key or insulin is in short supply or missing. so the cell door cant be opened and glucose floats freely in the blood stream to the kidneys( making them work harder) and the body doesn't get its needed energy. insulin can't be ingested by mouth due to the high acidic levels in digestion.this would destroy the polypeptides. Pork insulin ( lenti) has been used for years for people who develop insulin Resistance but is being phased out as are other animal derived hormones. synthetic insulin and islets cell transplants(being done in Canada,with success!) are the future of treating this syndrome.oral medication are not insulin but are used to regulate carb absorption or breakdown. oral meds are used at different times of day, alone or with insulin. they have even learned that woman who have PCOS ( who also run a higher risk of developing DM) can be treated with a glucose lowering agent called Glucophage.And new insulins like Lantus, allow better control with one injection a day.

obesity.  Insulin makes you gain weight.  Exercise after you eat and drink lots of waters. Check your levels and then do the corrections with your insulin.  You will give yourself less insulin.

i suggest that you talk about genetic engineering.\nto produce insulin for patients suffering from diabetes a bacteria is obtained and the plasmid DNA is extracted from it in addition to the insulin DNA which is extracted from a human the insulin DNA  is made part of the plasmid DNA and the plasmid is put back again into the bacteria. eventually the bacteria will produce insulin which is given to diabetes patients.

Most of the hormones produced in our bodies are excreted by the endoctrine system, the main contributor being the anterior and posterior pituitary.\n\nPosterior pituitary secretes 2 hormones: oxytocin (released during labor in women) and ADH (anti-diuretic hormone- released to increase sodium reabsorption when the body is dehydrated, low blood pressure, or in other cases when the body needs more water.)\n\nAnterior pituitary secretes many more hormones throughout your body, but the main ones are:\n\nFSH (follicle-stimulating hormone)\nLH (luteinizing hormone)\nACH (adrenocorticotropic hormone)\nTSH (thyroid-stimulating hormone)\nProlactin\nEndorphins (which make you happy)\n& GH (growth hormone)\n\nHope this helps.

Insulin secreted by the beta cells of the pancreas controls the blood glucose levels by stimulating body cells to increase the uptake and utilization of glucose; enhancing the formation of glycogen from glucose and by stimulating fat synthesis in liver. \n\nWhere as the other hormone GLUCAGON (secreted by the alpha cells of the pancreas) increases the blood glucose level when the level goes below normal. This is done by accelerating the breakdown of glycogen to glucose and by increasing the breakdown of fats to fatty acids and glycerol(this can be used as a source of energy instead of glucose).
