blood glucose concentration

• What hormones control blood glucose concentration?

  Insulin and glucagon
• What does blood glucose concentration refer to?

  It describes the amount of sugar in the bloodstream
• Why is it important to maintain a balance in blood glucose concentration?

  Because high levels can damage tissues and low levels can deprive cells of glucose
• What happens to blood glucose concentration after consuming a large meal high in carbohydrates?

  It increases as carbohydrates are broken down into glucose
• How does the pancreas respond to an increase in blood glucose concentration?

  It releases insulin into the bloodstream
• What role does insulin play in regulating blood glucose levels?

  It tells cells to take in glucose from the bloodstream
• Which cells are primarily responsible for taking up glucose in response to insulin?

  Liver and muscle cells
• What is glycogen?


  It is a long-term storage form of glucose
• What happens to blood glucose concentration after insulin is released?

  It decreases as glucose is taken up by cells
• What hormone is released when blood glucose levels drop too low?

  Glucagon
• How does glucagon function in the body?

  It increases blood glucose levels by promoting the breakdown of glycogen
• What would happen if a person skips breakfast and their blood glucose levels drop?

  The pancreas will secrete glucagon to raise blood glucose levels
• How do insulin and glucagon work together in the body?

  They create a negative feedback loop to maintain blood glucose levels
• What is the result of the negative feedback loop involving insulin and glucagon?

  It keeps blood glucose concentration around the right levels
• Why do blood glucose levels fluctuate rather than remain constant?

  Because insulin and glucagon are constantly released to adjust levels
