Insulin was highest 1 hour post meal and glucagon was highest 3 hr post meal

This means when blood glucose levels rise above the optimum level, the organ’s cells can’t absorb the glucose into the cells, and the liver can’t convert it into glycogen to store, like it usually would if insulin were present. (5) Type 2 diabetes is when the body doesn’t recognize the insulin and therefore cannot spread the glucose out of the blood to the rest of the body’s organs. As a result of the high levels of glucose, the pancreas (The Detector) detects this and as a result produces more insulin to help it spread through the body and lower the blood glucose levels. This keeps happening and is an example of a negative feedback system until the it eventually shuts down and no longer is produced. Both types of diabetes cause a disruption in the homeostatic process

Sugar is the primary fuel for the cells in the body, and the insulin takes the sugar from the blood and into the cells. When glucose builds

(TCO 4) After a meal, which hormone is responsible for moving glucose into the body's cells?

Graph 2 represents that patient A has a much lower initial glucose concentration than patient B. The glucose concentration of patient A reached its maximum in the first 30 minutes, this is due to the quick release of insulin from the body. Whereas, patient B had a slower reaction to releasing insulin which allowed for longer time to be taken for glucose concentration to reach its maximum. The sudden decrease of the glucose concentration in patient A displays the conversion of glucose molecules being stored as energy. In comparison, the gradual change of the slope show that as patient B releases small amount of insulin, it takes more time for glucose molecules to be converted as energy. It can be concluded that patient B has diabetes as the

Plasma glucagon concentration was at its highest during the 1 hour post meal time, at a concentration of 6.

Answer 1: Insulin and glucagon work together to keep glucose levels in the blood within the

After we eat, our bodies release insulin, a hormone that offsets an increase in blood glucose by increasing the intake of glucose by cells. When people have consumed little to no nutrients for several hours, our bodies secrete glucagon. Glucagon helps maintain the homeostasis of glucose by stimulating the breakdown of storage glycogen and the secretion of glucose to the blood and rest of the body.

leads to high sugar levels within the blood. Insulin is a hormone that takes the sugar from the

As your blood sugar level drops, so does the secretion of insulin from your pancreas.

The negative feed back loop plays into affect with diabetes. As we know diabetics don't produce enough insulin to keep them energized. The negative feed back loop can show us where they don’t make enough insulin. The loop starts of with the intestine absorbing the glucose after a meal. As we all know glucose is sugar, the second step is the blood glucose level rises. Then the pancreas responds to high glucose level by secreting insulin. This step is not valid for most diabetics, they can't produce insulin so that’s why when they eat they inject themselves with insulin. To continue the cycle the insulin is traveling across to the liver and other tissues to take up glucose, which removes it from the bloodstream. The fifth and final step, blood

Blood glucose is important as it is the ‘fuel’ that powers all cellular processes in our body. However the amount of glucose in our blood must be maintained carefully, the body must do this to ensure Homeostasis is maintained in response to external and internal environmental fluctuations. Homeostasis is the process through which bodily functions and chemicals are kept in a state of balance (stasis) allowing the body to function optimally. The mechanism that detects the changes in the internal environment away from the normal and acts to return it to a steady state is negative feedback. Negative Feedback has three functional components; a receptor, a control centre and an effector, each of these components work together to respond to fluctuations

Before blood continues to the heart, it must first travel through the liver to metabolize the substances from the GI tract. The carbohydrates that are in the food processing through the GI tract that is then transported to the liver is where it creates, stores, and releases glucose. At this point, the liver helps maintain a normal glucose levels within the blood flowing through the hepatic system. If sugar levels (glucose) were to start getting too high, the pancreas will start producing insulin to help the liver maintain the glucose levels. The drugs that the GI tract absorbs usually loses their potency before it reaches circulation of the blood because the liver processes and metabolizes them. At rest the liver consumes about 20% of total body

When food reaches the digestive track, it transforms into glucose. That is a simple sugar. It is absorbed by the stomach and intestine and then it enters to the blood stream. When it is in the blood stream, the sugar level of our body rises. This gives signals to the pancreas, resulting in the liberation of the hormone called insulin. This hormone is very important because it helps glucose to reach important parts of the human body, such as the liver, muscles and adipose tissue or fat. It is also necessary because it helps to maintain sugar levels of our body. When the Pancreas does not produce insulin, the blood sugar level rises and glucose cannot reach the liver, muscle, and adipose tissue. This defect is called diabetes. The international Expert Committee in their article “International Expert Committee Report On The A1c Assay In The Diagnosis Of Diabetes” states that “Diabetes is a disease characterized by abnormal metabolism, most notably hyperglycemia, and an associated heightened risk for relatively specific long-term complications

In a person without diabetes, the body keeps the plasma glucose level between meals in the range of 70-99 milligrams per deciliter. It will rise depending on how big your meal is, however, quickly returns to normal. In a person with diabetes, the blood glucose level rises abnormally high after eating, takes much longer to come down, and doesn’t return to normal range. Even during periods of fasting. Therefore. To determine if you have diabetes, a doctor must test your blood glucose levels
