Question

What happens when beta cells of the pancreas release insulin into the blood?

• A. Blood glucose levels rise to a set point and stimulate glucagon release.
• B. Body cells take up more glucose.
• C. The liver breaks down glycogen into glucose.
• D. Alpha cells are stimulated to release glucagon into the blood.

Answer 1

The correct option is B

Body cells take up more glucose.

When a person eats food rich in carbohydrates, the blood glucose level increases. This stimulates the secretion of insulin by β cells and inhibits the secretion of glucagon by the α cells. Insulin promotes the cellular uptake of glucose into liver and muscle cells, where it is stored as glycogen, and into adipose cells, where it is stored as fat.
