Question

Quizplus · Accepted Answer

Insulin helps lower blood glucose levels by promoting glucose uptake by cells, especially muscle and fat cells. It also stimulates glycogen synthesis in the liver and inhibits gluconeogenesis, thereby reducing glucose output by the liver. However, insulin does not facilitate the entry of glucose into brain tissue, as brain cells can transport glucose across the blood-brain barrier independently of insulin. Finally, insulin does not promote gluconeogenesis, but rather inhibits it.
