Model Answer
(a) Insulin is secreted by the pancreas and helps in lowering blood glucose levels by facilitating the uptake of glucose by body cells. Deficiency or improper functioning of insulin causes diabetes mellitus (sugar diabetes).
(b) The timing and amount of insulin released is regulated by feedback control — when blood sugar level rises, more insulin is secreted; when it falls back to normal, secretion reduces automatically.
