Secretion of insulin causes
A)a decrease in the concentration of blood glucose.
B)a decrease in the permeability of cell membranes to glucose.
C)an increase in the breakdown of glycogen to release glucose.
D)an increase in the concentration of blood glucose.

Question

Quizplus · Accepted Answer

Insulin is released in response to high blood glucose levels and it helps bring down the concentration of glucose in the blood by promoting the uptake of glucose by cells and the storage of excess glucose as glycogen. Insulin also inhibits the breakdown of glycogen to release glucose, which is why choice C is incorrect. Therefore, of the given choices, insulin secretion causes a decrease in the concentration of blood glucose (choice A). The other two choices are also incorrect as insulin promotes the permeability of cell membranes to glucose (choice B) and does not increase the concentration of blood glucose (choice D).
