Insulin: An elevated blood glucose concentration results in the secretion of insulin: glucose is transported into body cells. The uptake of glucose by liver, kidney and brain cells is by diffusion and does not require insulin.
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.1.1 Blood-brain Barrier Maintains the Constancy of the Brain's Internal Environment. The blood-brain barrier (BBB) protects the neural tissue from variations in blood composition and toxins.
