The passive transport supplies a cell with glucose. A passive transport is the diffusion of particles through the proteins. The particles move from an area of high concentrati â¦ on to an area of low concentration.
Carrier-mediated transport enables molecules with low lipid solubility to traverse the blood-brain barrier. 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.
