# A person eats a large meal high in carbohydrates. Explain how the body responds to restore normal blood glucose concentration after this meal.

> Pearson Edexcel A-Level Biology A (9BI0) — Topic 6 Response to Change · Explain · 5 marks

> After eating a meal rich in carbohydrates, blood glucose concentration rises above the normal level. The body detects this change and responds to bring blood glucose concentration back to normal.

## Mark scheme (5 marks)

1. The pancreas detects the rise in blood glucose concentration
2. The pancreas releases/secretes insulin (into the blood)
3. Insulin causes the liver (and muscle cells) to convert glucose to glycogen / remove glucose from the blood
4. Blood glucose concentration falls / returns to the normal level
5. This is an example of negative feedback / the corrective response reduces the original change
