Question

Model 2 - Feedback Control of Blood Glucose Pancreas .. Liver Other cells OO Blood glucose is too high. Cycle A Blood glucose drops. Baseline blood glucose level. Blood glucose rises. Glucose Insulin Glycogen Glucagon Cycle B Blood glucose is too low. 7. Where in the body does insulin and glucagon originate? 8. In what form is glucose stored in the liver and what is the consequence in terms of glucose blood levels? 10. Which hormone (insulin or glucagon) helps glucose move into cells of the body? 11. Which hormone (insulin or glucagon) helps turns glycogen into glucose and what is the consequence in terms of glucose blood levels when glycogen is broken down?

Answer 1

7: Insulin and Glucagon hormone are secreted by Islet cells in pancreas.They are both secreted in response to blood sugar level.Insulin is normally secreted by the Beta cells of pancreas.

8: Glucose is stored in liver as "Glycogen"

Animals(including human)store some glucose in the cells so that it is available for quick shot of energy.Excess glucose is stored in the liver as the large compound called glycogen.

The consequences of blood sugar level; *Untreated, low blood sugar can be very dangerous.It can result in the seizure,loss of consciousness or death,hyperglycemia and Hypoglycemia in type 2 diabetics.

* Having high blood sugar can cause serious health problems such as vision problem,heart stroke, kidney failure and nerves problem...

10: "Glucagon"works to counter-balance the action of Insulin.About 4 to 6 hours after we eat,the Glucose level in your body decrease,triggering your pancreas to produce glucagon.This hormone signals your liver and muscle cells to change the stored glucagon back into glucose.

11:Glucagon helps turn the glycogen into glucose

The consequences in term of glucose blood level when glycogen is broken down are as follows;

* when the body needs extra fuel,It Breaks down the glycogen stored in the liver back into the glucose units that cell can use.This can lead to very low blood glucose level during periods of fasting.The muscles and organs need a certain level of glucose in blood to work properly.Hence this leads to major health problems such as hypoglycemia and swollen belly because of enlarged liver...
