The islets of Langerhans are specialized tissues within the pancreas that contain three types of hormone-secreting cells: alpha, beta, and delta. Which one of these cells secretes the hormone insulin?
  1. Alpha
  2. Beta
  3. Delta
  4. Insulin is not a hormone.
Explanation
Answer - B - The hormone-secreting beta cell secretes the hormone insulin. Insulin is an antagonistic to glucagon and causes the blood level of glucose to decrease. It combines with insulin receptors on the cell membrane and allows glucose to enter the cell. Alpha cells secrete glucagon and delta cells secrete somatostatin.
