Answer:
d. helps regulate blood glucose
Step-by-step explanation:
The insulin hormone is secreted by beta cells of the endocrine portion of the pancreas. Insulin is released in response to raised blood glucose levels. The function of this hormone is to make the body cells to take up the glucose from the blood. It specifically targets the liver and muscle cells and makes them absorb glucose from the blood. The absorbed glucose is stored in the form of glycogen in these cells and the blood glucose levels are restored to the normal range.
