Answer:
Insulin is produced by the pancreas because it allows sugar from the blood to enter the cells and be used for energy.
Step-by-step explanation:
The most important hormone that the pancreas produces is insulin. Insulin helps the glucose get into the body's cells. Insulin is released by the 'beta cells' in the islets of Langerhans in response to food. Its role is to lower glucose levels in the bloodstream and promote the storage of glucose in fat, muscle, liver, and other body tissues.
