What is a primary function of insulin?

• A. Causing the liver to release glycogen
• B. Increasing the movement of glucose into the cells
• C. Increasing blood glucose levels
• D. Causing the liver to convert glucose to glucagon

Answer: (B)

The primary function of insulin is to increase the movement of glucose into the cells. Insulin is a hormone produced by the pancreas that plays a crucial role in glucose metabolism. When you eat, your blood glucose levels rise, prompting the pancreas to release insulin. This insulin facilitates the uptake of glucose by cells, particularly in muscle and fat tissues, which helps lower blood glucose levels and provides cells with the energy they need for various functions. By promoting glucose uptake, insulin ensures that cells can utilize glucose for energy, which is vital for maintaining proper metabolic balance. In this way, insulin helps regulate blood sugar levels, preventing hyperglycemia (high blood sugar) and allowing for efficient energy use in the body.
