Which function is NOT associated with insulin?

Insulin is a hormone primarily responsible for regulating blood glucose levels. Its main functions include enhancing the uptake of glucose by cells, particularly in muscle and fat tissues, which contributes to lowering blood glucose levels. Additionally, insulin promotes the conversion of glucose to glycogen in the liver for storage, further helping to maintain glucose balance in the body.

The function associated with producing glucose for energy is not a role of insulin. In fact, it is actually the opposite: insulin facilitates the uptake of glucose to be used for energy rather than producing it. The process of gluconeogenesis, where glucose is generated, typically occurs in response to low insulin levels or during fasting conditions.

Therefore, identifying the function that does not align with the roles of insulin, particularly the idea that insulin produces glucose, clarifies why that option stands apart from the other established functions of insulin.
