Control of Blood Glucose Flashcards
1
Q
what are the steps of normal blood glucose?
A
-potassium ion channel is open
- potassium diffuses out of the beta cell
- inside of the cell is relatively negative (-70mv)
- calcium ion channel is closed
2
Q
what are the steps of high blood glucose?
A
- blood glucose levels become high
- glucose enters by facilitate diffusion
- glucose is respired to form ATP is the mitochondria
- ATP belong the potassium channel
- membrane depolarises
- calcium ion channels open
- calcium diffuses into the beta cells
- causes the vesicles of insulin to be released by exocytosis
