homeostasis - blood glucose Flashcards
(15 cards)
why is glucose needed by every cell
to release energy by respiration
how is blood glucose concentration monitored
by the panaceas
when can blood glucose concentration rise
after eating a meal with carbohydrates
the pancreas detects this rise and so what does it produce
insulin
what is the role of insulin
- it triggers body cells to take up glucose from the blood
- it also triggers liver and muscle cells to store excess glucose as a storage molecule called glycogen
what happens if you have too much glucose in your body
you can end up with diabetes
what are the two types of diabetes you can get
type 1 and type 2
what happens in the body with type 1
the pancreas doesnt produce enough insulin
what do people with type 1 diabetes monitor
their blood glucose concentration and they have to inject themselves with insulin
what happens in the body with type 2 diabetes
the body cells stop responding to insulin produced y the pancreas
how is type 2 diabetes treated
with a diet containing a controlled level of carbohydrates
what is a major risk factor of type 2 diabetes
obesity
what happens in the body if the blood glucose concentration is too low
the pancreases releases a hormone called glucagon
what does glucagon trigger
triggers liver cells to convert glycogen into glucose
why do scientists say glucagon and insulin form a negative feedback cycle
because they have opposite effects
