Controlling Blood Glucose Concentration Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

What role does the pancreas play in regulating blood glucose concentration?

The pancreas regulates blood glucose concentration using the hormones insulin and glucagon.

What is the function of insulin in the body?

Insulin, produced by the pancreas, causes cells to take up glucose and stimulates the liver and muscle cells to convert glucose to glycogen for storage.

What happens to cells if blood glucose concentration is too high?

If blood glucose concentration is too high, cells lose water by osmosis, which can damage them.

How does glucagon affect blood glucose levels?

Glucagon stimulates liver and muscle cells to break down glycogen into glucose and release it into the bloodstream, increasing blood glucose levels.

What happens when blood glucose levels are too low?

When blood glucose levels are too low, the pancreas releases glucagon, which stimulates glycogen breakdown in the liver, converting it into glucose and raising blood glucose levels back to normal.

Describe the process that occurs when blood glucose levels are too high.

When blood glucose levels are too high, the pancreas releases insulin, which stimulates the liver to convert glucose into glycogen and causes cells to take up glucose, lowering blood glucose levels back to normal.
