A Mother of a Toddler Who Recently Diagnosed with Diabetes

A mother of a toddler who recently diagnosed with diabetes type 1 asks the nurse why her child can't be given oral antidiabetics instead of insulin. The nurse would explain that oral medication would not work for the baby because they:

A) enhance the release of glycogen from the liver.
B) enhance the transport of glucose into the cell.
C) stimulate the release of glucagons from the pancreas to produce insulin.
D) stimulate the beta cells of the pancreas to produce insulin.
