TRIPLE SCIENCE: Controlling Blood Glucose

HideShow resource information
Where does sugar in the blood come from?
Digested food and drink.
1 of 9
What are two hormones involved in controlling blood glucose levels?
Insulin & glucagon.
2 of 9
Explain how blood sugar level is controlled when there is too much glucose in the blood.
Insulin is released by the pancreas. This makes the liver store glucose. Excess blood glucose is converted to starch. Glycogen is removed from the glucose. Blood glucose level is now lower.
3 of 9
Explain how blood sugar level is controlled when there is too little glucose in the blood.
Glucagon is secreted by the pancreas - this makes the liver turn glycogen into glucose. Glucose is added by the liver into the blood - this increasing blood glucose levels.
4 of 9
What is type 1 diabetes?
When your body releases too little or no insulin to control blood sugar levels.
5 of 9
What is type 2 diabetes?
When the body doesn't produce enough insulin, or the body's cells don't react to the insulin. Often associated with obesity.
6 of 9
Describe a major improvement that has been made to the source of insulin used by diabetics.
Used to use insulin from animals such as pigs. Now use human insulin made from genetically modified bacteria. This causes less adverse reactions in patients.
7 of 9
Name two problems with having a pancreas transplant.
1. Have to take immunosuppressive drugs. 2. Could be rejected by the body.
8 of 9
Name two treatments for diabetics that are in development.
1. Artificial pancreas. 2. Using stem cells.
