What role does insulin play in blood glucose regulation?

• A. It increases blood glucose levels
• B. It facilitates glucose uptake into cells
• C. It blocks glucose from entering cells
• D. It regulates blood lipids

Answer: (B)

Insulin plays a crucial role in regulating blood glucose levels by facilitating the uptake of glucose into cells. After a meal, blood sugar levels rise, and insulin is released from the pancreas in response. This hormone binds to insulin receptors on the surfaces of cells, particularly in muscle and fat tissues, allowing glucose to enter these cells. Once inside, glucose can be utilized by the cells for energy or stored as glycogen for later use. By promoting this uptake, insulin helps lower blood glucose levels, maintaining homeostasis within the body. Therefore, understanding the function of insulin in this capacity is vital, as it directly impacts how the body manages energy and maintains stable blood sugar levels.
