Producing insulin to regulate metabolism

Explanation:

The production of insulin is the main feature of pancreatic cells that helps in the regulation of blood glucose level.

The main function of insulin in the body is to decrease the blood glucose level to make it normal.

The normal blood glucose level should not be more than 120 mg/dL at the time of fasting, so insulin regulates the metabolism by lowering the blood glucose level which is a function of pancreas.
