, 15. The hormone insulin enhances the transport of glucose (sugar) from the blood into most of the
body’s cells. Its secretion is controlled by a negative-feedback system between the concentration
of glucose in the blood and the insulin-secreting cells. Therefore, which of the following
statements is correct?
a. A decrease in blood glucose concentration stimulates insulin secretion, which in
turn further lowers the blood glucose concentration.
b. An increase in blood glucose concentration stimulates insulin secretion, which in
turn lowers the blood glucose concentration.
c. A decrease in blood glucose concentration stimulates insulin secretion, which in
turn increases the blood glucose concentration.
d. An increase in blood glucose concentration stimulates insulin secretion, which
further increases the blood glucose concentration.
