Glucose from blood enters the brain by a transport protein. Glucose is the primary energy substrate of the brain. Glucose transport protein (GLUT-1) is highly enriched in brain capillary endothelial cells.These transporters carry glucose molecules through the blood brain barrier.lucose is the primary energy substrate of the brain.

Seeing the changing autumn leaves is a longstanding Colorado tradition that generally takes place mid-September to mid-October each year, and AAA Colorado, the Colorado Department of Transportation (CDOT), and Colorado Parks and Wildlife want to let people know where to drive and how to drive safely for some of the best views this season.
Or they should, anyway. While leaves will always change color as the amount of sunlight wanes, several weather conditions can affect how brilliant they become. High heat or drought can rob leaves of their brilliance, or make leaves drop early. Insufficient rain in September can also hurt peak color.
