Practice Questions

1.Explain how insulin lowers blood glucose concentration

Insulin is released by the pancreas when blood glucose is too high.

Glucose moves from the blood into body cells — especially liver and muscle cells.

In liver and muscle cells, excess glucose is converted into glycogen for storage.

This reduces the concentration of glucose in the blood back to normal.

2.Name the storage form of glucose in liver and muscle cells.

Glycogen

3.Explain why people with Type 2 diabetes may need a controlled diet and regular exercise.

People with Type 2 diabetes may need a controlled diet to reduce the amount of glucose entering the blood, and regular exercise to help body cells take up and use glucose. This helps to lower blood glucose levels and maintain them closer to normal.
