Answer
Exam answer
INSULIN (secreted by the beta cells of the islets of Langerhans in the pancreas).
Explanation
Insulin LOWERS blood glucose, by making the body cells take it up and the liver store it as glycogen. Without enough insulin, glucose accumulates in the blood and spills over into the urine — which is why the urine of a diabetic contains sugar.
MELLITUS means honey-sweet, and that is precisely why: physicians once diagnosed the disease by the sweetness of the urine.
