Controlling blood glucose

    Cards (17)

    • What hormones control blood glucose concentration?
      Insulin and glucagon
    • What does blood glucose concentration refer to?
      Amount of sugar in the bloodstream
    • Why do cells need a constant supply of glucose?
      For respiration to produce energy
    • What happens if blood glucose concentration gets too high?
      It can damage our tissues
    • What occurs when a person eats a large meal with carbohydrates?
      Blood glucose concentration increases
    • How does the pancreas respond to high blood glucose levels?
      It releases insulin into the bloodstream
    • What is the role of insulin in blood glucose regulation?
      It tells cells to take in glucose
    • Which cells are most important for glucose uptake?
      Liver and muscle cells
    • What is glycogen?
      A long-term storage form of glucose
    • What happens to blood glucose concentration after insulin is released?
      It decreases back to normal levels
    • What hormone is released when blood glucose levels are low?
      Glucagon
    • How does glucagon affect blood glucose levels?
      It increases blood glucose concentration
    • What does glucagon do to glycogen in the liver?
      It breaks it down into glucose molecules
    • What is the relationship between insulin and glucagon?
      They create a negative feedback loop
    • How does the body maintain blood glucose levels?
      By releasing insulin and glucagon as needed
    • Why do blood glucose levels fluctuate rather than remain constant?
      Due to continuous release of hormones
    • What is the process of blood glucose regulation involving insulin and glucagon?
      • High glucose: Insulin released
      • Cells take in glucose
      • Glucose stored as glycogen
      • Low glucose: Glucagon released
      • Glycogen broken down to glucose
      • Glucose released into blood
