Which hormone is secreted by the beta cells of the Islets of Langerhans in response to elevated blood glucose levels?
Answer and explanation
Correct answer: B. Insulin
- Step 1: When blood glucose levels rise after a meal, the chemoreceptors in the pancreas detect the increase and stimulate the beta cells of the Islets of Langerhans.
- Step 2: The beta cells secrete insulin into the bloodstream, which promotes glucose uptake into cells and stimulates glycogenesis (the conversion of glucose into glycogen in liver and muscle cells) to lower blood glucose back to normal levels.
Answer
Insulin.
