What is the effect of insulin on blood sugar levels?

• Increases blood sugar levels

• Decreases blood sugar levels

• No effect on blood sugar levels

• Converts glucose to protein

Explain how exercise affects blood glucose levels.

• Exercise increases blood glucose levels by releasing stored glucose.

• Exercise decreases blood glucose levels by increasing insulin and breaking down glucose.

• Exercise has no effect on blood glucose levels.

• Exercise decreases blood glucose levels by decreasing insulin production.

Describe the role of glucagon in blood sugar regulation.

• Glucagon decreases blood sugar levels by promoting glucose uptake.

• Glucagon increases blood sugar levels by promoting glucose release.

• Glucagon has no role in blood sugar regulation.
