The 20 questions

  1. Which organ monitors and controls blood glucose concentration?

    • The liver only
    • The brain
    • The pancreas
    • The kidney

  2. What hormone does the pancreas produce when blood glucose is too high?

    • Glucagon
    • Oestrogen
    • Insulin
    • Adrenaline

  3. Where does insulin cause glucose to move from the blood?

    • Into digestive enzymes
    • Into body cells
    • Into urine
    • Into the gut

  4. In liver and muscle cells, what is excess glucose converted to for storage?

    • Starch
    • Glycogen
    • Urea
    • Ethanol

  5. What primary malfunction causes Type 1 diabetes in the human body?

    • High carbohydrate intake
    • Excess glucagon production
    • Insulin receptor damage
    • Insufficient insulin production

  6. How is Type 1 diabetes normally treated?

    • Vaccines given yearly
    • Painkillers given daily
    • Insulin injections
    • Antibiotics given daily

  7. What is the primary cause of Type 2 diabetes?

    • Pancreas fails completely
    • Cells resist insulin
    • Excess insulin production
    • Lack of glucagon

  8. Which lifestyle treatment is commonly used for Type 2 diabetes?

    • High-protein diet
    • Carbohydrate-controlled diet
    • Antibiotic medication
    • Daily insulin injections

  9. Which health factor is a major risk factor for Type 2 diabetes?

    • High blood pressure
    • Obesity
    • Smoking
    • Malnutrition

  10. What blood condition characterises untreated Type 1 diabetes?

    • Low oxygen concentration
    • High glucose concentration
    • Low glucose concentration
    • High red blood count

  11. (HT only) Which hormone is produced when blood glucose is too low?

    • Adrenaline
    • Glucagon
    • Oestrogen
    • Insulin

  12. Which molecule is stored glycogen broken down into by glucagon?

    • Galactose
    • Glucose
    • Glutamate
    • Glycerol

  13. What type of control mechanism do insulin and glucagon use together?

    • Reflex response
    • Positive feedback
    • Negative feedback
    • Osmotic balance

  14. In which organs is excess glucose stored as glycogen?

    • Pancreas and stomach
    • Brain and kidneys
    • Liver and muscles
    • Lungs and heart

  15. Which organ monitors and controls blood glucose concentration in humans?

    • Pancreas
    • Brain
    • Kidney
    • Liver

  16. What causes Type 1 diabetes compared to Type 2 diabetes?

    • Insulin receptor damage
    • Insufficient insulin secreted
    • Cells resist insulin
    • High carbohydrate intake

  17. What happens to blood glucose levels if insulin is not injected by a Type 1 diabetic?

    • Drops rapidly
    • Remains constant
    • Fluctuates normally
    • Rises uncontrollably

  18. Why is exercise recommended for people with Type 2 diabetes?

    • Destroys pancreatic cells
    • Stops glycogen breakdown
    • Lowers blood glucose
    • Increases insulin production

  19. Into which storage carbohydrate is excess glucose converted in liver and muscle cells?

    • Glycerol
    • Glycogen
    • Starch
    • Glucagon

  20. Which hormone is released by the pancreas when blood glucose levels fall too low?

    • Insulin
    • Glucagon
    • Glycogen
    • Thyroxine
