The 20 questions

  1. Which cells are destroyed by the immune system in Type 1 diabetes?

    • Alpha cells
    • Delta cells
    • Beta cells
    • Acinar cells

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

    • Insulin resistance
    • Glucagon deficiency
    • Beta cell destruction
    • Insulin shortage

  3. What is the primary medical treatment for Type 1 diabetes?

    • Glucagon injections
    • Oral metformin
    • Insulin injections
    • Dietary changes alone

  4. What is usually the first-line management strategy for Type 2 diabetes?

    • Pancreas transplant
    • Lifestyle changes
    • Immunotherapy
    • Insulin injections

  5. How is synthetic human insulin for medical use mainly produced today?

    • Chemical synthesis
    • Extraction from pigs
    • Human blood donation
    • Genetically modified bacteria

  6. Which potential treatment uses cells that can develop into many different cell types?

    • Neurones
    • Red blood cells
    • Platelets
    • Stem cells

  7. Why must therapeutic insulin be injected rather than taken orally as a tablet?

    • Insoluble in water
    • Mutates DNA cells
    • Absorbed too quickly
    • Digested by proteases

  8. Which substance is present in the urine of a person with uncontrolled diabetes?

    • Glucagon
    • Glucose
    • Protein
    • Urea

  9. What happens to blood glucose concentration if a Type 1 diabetic misses their insulin?

    • It drops to zero
    • It increases
    • It remains stable
    • It decreases

  10. Which factor significantly increases the risk of developing Type 2 diabetes?

    • Obesity
    • Youth
    • Low blood pressure
    • Regular exercise

  11. In Type 2 diabetes, why do target cells fail to take up glucose?

    • Beta cell destruction
    • Reduced receptor sensitivity
    • Excess glucagon secretion
    • Absence of insulin

  12. What is an advantage of using bacteria to produce human insulin?

    • Cures diabetes permanently
    • Requires no purification
    • No allergic reactions
    • Zero production cost

  13. Which pancreatic cells are produced from stem cells to treat Type 1 diabetes?

    • Delta cells
    • Beta cells
    • Acinar cells
    • Alpha cells

  14. What is the primary physiological effect of an insulin injection?

    • Raises blood glucose
    • Destroys alpha cells
    • Lowers blood glucose
    • Inhibits glycogen synthesis

  15. What dangerous condition is caused by injecting too much insulin?

    • Glycosuria
    • Ketoacidosis
    • Hypoglycaemia
    • Hyperglycaemia

  16. When does Type 1 diabetes typically first develop in a patient?

    • Old age
    • Childhood or adolescence
    • Before birth
    • Late adulthood

  17. What main advantage does stem cell therapy offer over insulin injections in treating diabetes?

    • Lower infection risk
    • Permanent insulin production
    • Oral administration option
    • Immediate blood cleansing

  18. Which factor makes GM bacteria a more reliable source of insulin than animal pancreases?

    • Higher storage temperature
    • Consistent batch quality
    • Variable molecular structure
    • Slower cell division

  19. What is the main underlying cause of Type 2 diabetes?

    • Zero insulin production
    • Glucagon deficiency
    • Reduced insulin sensitivity
    • Autoimmune beta-cell destruction

  20. Which condition strictly requires daily insulin injections for survival?

    • Type 2 diabetes
    • Gestational diabetes
    • Type 1 diabetes
    • Diabetes insipidus
