Regulating Blood Glucose Concentration Flashcards
All 4 cards in this deck
Which endocrine gland and which hormone control blood glucose concentration?
The pancreas — insulin.
What are the steps by which insulin lowers blood glucose concentration?
e.g. after eating a meal containing carbohydrate
- Blood glucose rises, so the pancreas releases (more) insulin.
- Insulin makes the liver and muscle cells absorb glucose.
- Glucose is converted to / stored as glycogen, or used in respiration — so blood glucose falls.
True or false? Insulin raises blood glucose concentration.
False. Insulin lowers blood glucose concentration.
In a healthy person, what trend is seen in blood glucose concentration in the hour after a meal?
It increases first, then decreases back towards the pre-meal level as insulin is released.
