In hyperglycemia, elevated blood glucose levels occur when the body cannot effectively utilize glucose for energy due to a deficiency of insulin or insulin resistance. When glucose accumulates in the bloodstream, this can lead to a range of detrimental effects, notably when blood glucose levels reach between 200-500 mg/dL.

The inability of glucose to enter cells means that despite high levels of glucose in the blood, they cannot be converted into energy, resulting in excessive blood sugar levels. This condition can cause symptoms such as increased thirst, frequent urination, fatigue, and in severe cases, it may lead to serious complications like diabetic ketoacidosis or hyperglycemic hyperosmolar state.

The other options, while they may relate to general metabolic pathways or descriptions of conditions, do not accurately depict the physiological process occurring in hyperglycemia as thoroughly as the correct choice does. The accumulation of glucose specifically and the corresponding blood glucose level range are critical for understanding the implications of hyperglycemia in patients.
