This deep dive covers When Blood Glucose is TOO LOW (not eaten) within Glucose Regulation for GCSE Biology. Topic 6: Glucose Regulation It is section 3 of 15 in this topic. Use this deep dive to connect the idea to the wider topic before moving on to questions and flashcards.
When Blood Glucose is TOO LOW (not eaten)
- Pancreas detects low blood glucose
- Alpha cells in pancreas release GLUCAGON
- Glucagon travels in blood to liver
- Glycogen is converted back into glucose
- Glucose released into blood
- Blood glucose increases back to normal
Practice questions for Glucose Regulation
Which organ monitors blood glucose concentration and secretes insulin and glucagon?
Explain how blood glucose concentration is raised when it falls below the normal level.
Quick recall flashcards
What is glycogen and where is it stored?
Glycogen is the storage form of glucose. It is stored in the liver and in muscle cells. The liver can convert glycogen back to glucose when blood glucose falls too low.
What does insulin do when blood glucose is too high?
Insulin is released by the pancreas. It causes body cells to take up glucose from the blood, and causes the liver to convert excess glucose into glycogen for storage. Blood glucose falls.
