Question

Quizplus · Accepted Answer

Insulin is a hormone produced by the pancreas that lowers blood glucose levels by facilitating the uptake of glucose by cells, especially in the liver, muscle, and adipose tissue. It does not promote glucose output by the liver, and while some insulin receptors are present in the brain, insulin does not facilitate the entry of glucose into brain tissue as the brain can receive glucose even without insulin. Therefore, the correct answer is C, "It lowers blood glucose levels."
