Regulation of Blood Glucose
Flashcards do conjunto (12)
- 1What is the group of cells which produce Insulin and Glucagon called?Islets of Langerhans
- 2Which type of cells produce Glucagon?α Cells, these are larger than β cells.
- 3Which type of cells produce insulin?β Cells, these are smaller than α cells.
- 4What methods does insulin use to lower blood glucose.Increasing rate of absorption into cells. Increases rate of respiration.
Increases glycogenesis
Increases the conversion of glucose to fat - 5What methods does glucagon use to raise blood sugar levels?Activates an enzyme which converts glycogen to glucose.
Increasing the rate of gluconeogenesis. - 6What is gluconeogenesis?The conversion of glycerol and amino acids into glucose.
- 7What is glycogenesis?The conversion of glucose into glycogen.
- 8What is glucagon?A hormone produced by the α cells of the Islets of Langerhans in the pancreas which bring round effects which increase the level of glucose in the blood.
- 9What is insulin?A hormone produced in the β cells of the Islets of Langerhans in the pancreas which bring round effects which lower the level of glucose in the blood.
- 10What is the secondary messenger model?A mechanism which uses two hormones to regulate a process such as blood glucose. The first hormone binds a receptor site which activates an enzyme to convert ATP into Cyclic AMP which acts as the secondary messenger which activates another enzyme to breakdown Glycogen into glucose.
- 11Which type of diabetes is insulin independent?Type 2. This type of diabetes is usually down to the glycoprotein receptors on body cells becoming less responsive to insulin.
- 12Which type of diabetes is insulin dependent?Type 1. This type is down to the body being unable to produce insulin which could be down to an autoimmune response.
