  1. What does the liver do when insulin arrives?

    • Releases glucose into blood
    • Stores glucose as glycogen
    • Stops all work

  2. Blood glucose is high after lunch. What does the pancreas release?

    • Insulin
    • Glucagon
    • Adrenaline

  3. Glucagon raises blood glucose between meals.

    Circle one:   True   False

  4. Which fault marks type 1 diabetes?

    • The body ignores its insulin
    • The liver stores too much
    • The pancreas makes little or no insulin

  5. 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

  6. In type 2, cells answer insulin poorly and supply can fall short of need. What does this mean for control?

    • Only food choices matter, and medicines never help
    • Only the insulin supply matters, not the response
    • Both response and supply can need support

  7. In type 2, the body always makes more than enough insulin.

    Circle one:   True   False

  8. Trace A shows almost no insulin signal after a meal. Trace B shows plenty of signal but glucose stays high. Which match is right?

    • A shows missing supply and B shows poor response
    • A shows poor response and B shows missing supply
    • Both traces show the same break

  1. Stores glucose as glycogen · Insulin tells the liver to bank glucose as glycogen.
  2. Insulin · High glucose triggers insulin, which pulls the level back down.
  3. True · Low glucose triggers glucagon, and the liver releases stored glucose.
  4. The pancreas makes little or no insulin · In type 1 the pancreas makes little or no insulin, so the high-side signal is missing.
  5. Where the line falls after a peak · In this story graph, a falling line after a peak shows insulin pulling glucose down into stores.
  6. Both response and supply can need support · In type 2 the response is poor and supply can also fall short, so support varies and medicines differ.
  7. False · In type 2 the response is poor and supply can also fall short, so always-enough is false.
  8. A shows missing supply and B shows poor response · Almost no signal matches missing supply. Plenty of signal with high glucose matches poor response.
