Question

Quizplus · Accepted Answer

Large molecules such as glucose and vitamins cannot diffuse across the cell membrane or through ion channels. Transcytosis involves the uptake of material at one end of a cell, internalization of the material, and exocytosis at the other end, which is not a common mechanism for the transport of large molecules to the brain. Therefore, the only option left is special transport systems, which are necessary for the selective and efficient uptake of large molecules by the brain.
