Correct Response: C. In type 2 diabetes, cells become resistant to insulin, a hormone that helps cells absorb glucose from the blood. People with type 2 diabetes tend to have excess blood glucose as a result. Uptake of glucose by muscle cells during exercise is insulin-independent, making exercise an effective method of reducing blood glucose levels without the need of insulin. Hemophilia (A) is a genetic disorder in which blood fails to clot properly. It is not affected by blood glucose levels. Iron is an important component of hemoglobin that allows the protein to bind to oxygen. In iron-deficiency anemia (B), the lack of sufficient iron leads to a lack of healthy red blood cells. This limits the amount of oxygen that can be delivered to the body but does not affect blood glucose levels. Because of the liver's role in glucose homeostasis, liver disease can be caused by and/or contribute to diabetes and is therefore connected to blood glucose levels. However, since there are many causes of liver disease other than diabetes, option D is not the best answer.
