Diabetes occurs when the pancreas does not produce enough insulin or when the body does not use insulin properly (called insulin resistance). When levels of blood sugar rise, whether as a result of glycogen conversion, or from digestion of a meal, a different hormone is released from beta cells found in the islets of Langerhans in the pancreas. Before meals, the target blood sugar range is less than 95 mg/dL. Insulin is a hormone which plays a number of roles in the body's metabolism. Synthetic glucagon triggers your liver to release stored glucose, which then raises blood sugar.

Glucose Production and Utilization in Phase II, the Postabsorptive As cells absorb blood sugar, levels in the bloodstream begin to fall. Hyperglycemia refers to high blood sugar levels. Fatty acids are more energy rich but glucose is the preferred energy source for the brain and glucose also can provide energy for cells in the absence of oxygen, for instance during anaerobic exercise. How our bodies do this is studied in GCSE biology. Just one small thing, on the slide "blood insulin too low" Point 3 says "blood with too much glucose" rather than blood with too little glucose. even after three months. Glucagon increases your blood sugar level and prevents it from dropping too low, whereas insulin, another hormone, decreases blood sugar levels. This hormone, insulin, causes the liver to convert more glucose into glycogen (this process is called glycogenesis), and to force about 2/3 of body cells (primarily muscle and fat tissue cells) to take up glucose from the blood through the GLUT4 transporter, thus decreasing blood sugar. However, the body does not use all of this glucose at once. Glucose is very important because its the primary source of energy for your brain. Glucagon often causes vomiting, so when it is used the person should be kept on his/her .

Beta cells release insulin while alpha cells release glucagon. Glycogen may be released by the liver for a number of reasons, including: In these situations, when the body feels extra glucose is needed in the blood, the pancreas will release the hormone glucagon which triggers the conversion of glycogen into glucose for release into the bloodstream.

The insulin transduction pathway is a biochemical pathway by which insulin increases the uptake of glucose into fat and muscle cells and reduces the synthesis of glucose in the liver and hence is involved in maintaining glucose homeostasis.This pathway is also influenced by fed versus fasting states, stress levels, and a variety of other hormones. For example, when certain situations occur (like eating a large carb-heavy meal), the beta cells in the pancreas instruct the release of insulin. Instead, it converts some into storage molecules called glycogen and stores them in the liver and muscles. CHO and fat are oxidized to CO2 and H2O The bodys cells need glucose for energy, and insulin enables glucose to enter the cells. If there is excess energy, insulin drives glucose into glycogen creation in the muscles and liver. what causes type 2 diabetes bbc bitesize webmd.
