Why does decreased insulin cause diabetes?
Insulin is what catabolises (breaks down) glucose following a high carbohydrate meal. Diabetes has 4 types: only type 1 diabetes is related to insulin (seen in children and adolescents). It is called Insulin-Dependent Diabetes. Diabetes is basically very high levels of glucose found in the blood (greater then 250mg/dl) after testing. Where, normal fasting ranges of glucose = 70-110mg/dl Type 1: If their is a severe lack of insulin in the body. Glucose is unable to be broken down by the body (by stomach juices), because glucose is "dependent" upon insulin to be broken down causing diabetes (high levels of glucose in the body).

What are the basic steps of blood glucose regulation?
I know three out of six steps. 1. ? 2. Blood glucose levels increase. 3. ? 4. Glucose is stored in the liver. 5. ? 6. The pancreas releases glucagon. By Group 935[Chris]
What can cause hypoglycaemia?
There are a number of causes for low glucose.. 1) Low dietary intake 2) Diabetes mellitus as in no insulin release 3) Taking an insulin injection/parenteral insulin 4) Bacteria can cause it as they will eat it all up if u have bacterimea
What does insulin do to blood glucose?
Insulin response comes about from receptor tyrosine kinase. When insulin binds to the alpha portion of the RTK, the receptors dimerize. This results to its beta intracellular portion to autophosphorylate. This creates a binding site for IRS-1. When IRS-1 is activated, it recruits glut-4 receptors, allowing glucose to be taken in from the blood (therefore blood conc. will fall under insulin)
How does insulin regulate blood sugar in your body?
Insulin is released by the pancreas, and serves two important functions in blood-glucose control. Firstly, it encourages muscle and liver cells to take glucose from the blood. This is all very well, but glucose is soluble in the cytoplasm, and this poses a problem for osmoregulation, in the cells, so insulin also stimulates the conversion of glucose into glycogen - an insoluble sugar, which can then be stored until it is needed for respiration by cells.
How does glucose enter blood cells to synthesize ATP?
This is a typical muscle cell, you the insulin receptor at the top of page within the membrane of the cell. That insulin receptor sends a signal over to the Glut 4 glucose channel in the membrane to the left of the insulin receptor in which sugers enter the cell. The insulin hormone also sends many signals all over the inside of the cells cytoplasm, and into the nucleus on the bottom of page where transcription of genes takes place. In this case a growth hormone is made from a gene, and that growth hormone regulates the insulin and thereby the uptake of glucose into the cell. A type of negative feedback inhibition loop system, so the cell doesn't get too much intake of suger. That growth hormone controls this from happening. David Hagert Researcher medical
What diabetic patient needs insulin?
Always check your blood glucose level before administering insulin. Your brain must have glucose to function. If you take insulin when your blood glucose level is already low (below 70 mg/dl) you could lose consciousness and die. A good rule to remember is high and dry. If your level is low you are more likely to be somewhat sweaty and many people feel funny, confused or have vision problems. Normally, insulin is given just before a meal and you already know what the blood glucose level is. Carbohydrates supply your body with glucose. After a meal the body has a large amount of glucose available for use as fuel and insulin makes the glucose available to cells or to the liver for conversion of glucose to glycogen. Consider glycogen to be the glucose reserves for between meals. There are several types of insulin available, each with its own characteristics. The most rapid acting insulins: Lispro and Aspart can start taking effect in as little as 10-15 minutes with peak action occurring in around 60-90 minutes with a duration of effect lasting around 3-4 hrs. You would take these 10-15 minutes before a meal and as your food digested the peak action would offset all of that available glucose and help keep the levels in a normal range (somewhere around 100, higher in the elderly). This is called a bolus dose. Normally an intermediate acting insulin is given along with the shorter acting insulin to provide insulin in the body until the evening meal. This is called a basal dose. There are insulins available that have a more constant action and have a duration that lasts 24+ hrs. With these there are no peaks and you only need one shot of this per day. These are the long lasting insulins glargine and detemir. They take effect in 1-2 hours, but they are much more expensive.
Does insulin have to be taken daily?
4 a day
