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 slightest changes in weather in September - too warm, too cold, too wet, too dry - can slow color change or cause trees to drop leaves before they change color. Because it is too dry to produce the vibrant reds, yellows, and oranges, a severe summer drought will create a landscape filled with the subtler colors of tans, bronzes and auburns.
