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.
Re: Banff Best Time for Fall Color _ Leaves. May 23, 2008, 10:23 AM. Yes, the latter part of September tends to be best. Note that the 'leaf' colour change is mostly larch needles at high elevations (especially in the Lake Louise area), as well as some leafy trees and bushes mostly in valley bottoms. Most mountainsides stay green year-round.
