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.
The elk rut takes place between the middle of August and the middle of October, depending on the climate in which they live. The elk rut occurs around the same time of year throughout the United States. For example the peak rut in Idaho occurs between September 20 and 25, while the peak rut in New Mexico occurs around September 14. The rut tends to last somewhere between 20 and 45 days. This varies on latitude, for in southern areas spring arrives earlier and fall arrives later giving elk a longer calving season, therefore the rut lasts longer.
