Answer:
A. Insulin
Explanation:
Insulin is a hormone produced by beta cells in the pancreas. It main job is to keep glucose levels within the healthy range by allowing cells to absorb glucose from the bloodstream.
Glucose is a form of energy that comes from food. It is broken down from carbohydrates, then released into the bloodstream. After this, insulin tells your cells to absorb the glucose to use it for energy. If there is too much glucose, insulin tells your liver to absorb the glucose until it is needed.
If your pancreas does not produce insulin or your body does not respond to it, that is called diabetes. To learn more about diabetes, check out https://brainly.com/question/32174319
