3short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is response to high blood glucose?Show answer
After a meal, blood glucose rises. The pancreas detects this and releases insulin. Insulin causes:
What is response to low blood glucose?Show answer
Between meals or during exercise, blood glucose falls. The pancreas detects this and releases glucagon. Glucagon causes:
What is reading a blood glucose graph?Show answer
A common exam stimulus is a graph of blood glucose concentration over several hours, showing peaks after meals and troughs between them. To interpret it, link each feature to the hormone responsible. At a peak just after eating, glucose is high, so insulin secretion is high and the line then falls as glucose is taken up and stored. In a trough between meals or during exercise, glucose is low, so glucagon secretion rises and the line climbs back toward the set point.
