Insulin is the peptide hormone that is secreted by the beta cells of the pancreas in the blood when the concentration of glucose becomes more than an appropriate level in the blood.
It reduces the extra glucose in the blood by storing it in the form of glycogen in the body. By doing this it helps in maintaining the blood sugar level and protect the body from hyperglycemia.
Alpha cells of the pancreas release another hormone called glucagon which works antagonistic to insulin by raising the blood glucose level. So the given statement is false.
