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.
As the trees zap the water out of the leaves, the result is that the leaves slowly change color, dry up, and fall off. So the trick is to look for a cold, dry snap in weather, which basically means predicting when the leaves will change color in the Smoky Mountains is about as hard as predicting the weather!
