Question

Quizplus · Accepted Answer

Insulin promotes the insertion of additional glucose transporters in the plasma membranes of insulin-dependent cells, which helps to increase glucose uptake. It also stimulates glycogenesis (the process of converting excess glucose into glycogen for storage) and inhibits glycogenolysis (the breakdown of glycogen into glucose). Insulin secretion is increased in response to a fall in blood glucose concentration, which helps to raise blood glucose levels back to normal. Therefore, choices A, B, and C are all correct, making answer D the best choice.
