What does the liver do when insulin arrives?
- Releases glucose into blood
- Stores glucose as glycogen
- Stops all work
Blood glucose is high after lunch. What does the pancreas release?
- Insulin
- Glucagon
- Adrenaline
Glucagon raises blood glucose between meals.
Circle one: True False
Which fault marks type 1 diabetes?
- The body ignores its insulin
- The liver stores too much
- The pancreas makes no insulin
On a glucose against time graph, where was insulin acting?
- Where the line climbs before a meal
- Where the line falls after a peak
- Where the line stays flat overnight
Why do diet and exercise come first for type 2?
- They replace missing insulin directly
- They remove the pancreas
- They help the body answer its own insulin again
Type 2 diabetes is treated first with insulin injections.
Circle one: True False
Two patients: one makes no insulin, one ignores it. Who gets insulin injections first?
- The one who makes none
- The one who ignores it
- Both equally

For grown-ups. Fold this page away before handing over the rest.

Stores glucose as glycogen · Insulin tells the liver to bank glucose as glycogen.
Insulin · High glucose triggers insulin, which pulls the level back down.
True · Low glucose triggers glucagon, and the liver releases stored glucose.
The pancreas makes no insulin · In type 1 the pancreas makes no insulin, so supply must be replaced.
Where the line falls after a peak · A falling line after a peak shows insulin pulling glucose down into stores.
They help the body answer its own insulin again · Type 2 still makes insulin but ignores it, so retraining the response comes first.
False · Diet, movement, and weight control come first for type 2, since the body still makes insulin but ignores it.
The one who makes none · No supply means replacement by injection, while ignored supply is retrained first.
