carrier-mediated transport

carrier-mediated transport

The transport of a molecule from point A, usually on one side of a cell (e.g., external to the cell), to point B via a transmembrane carrier.

Properties
• Chemical specificity;
• Competitive Inhibition;
• Non-competitive inhibition.

The topics are the structural basis of movement across cell membranes, simple diffusion the non-electrolytes and ions, ion channels across cell membranes, carrier-mediated transport: facilitated diffusion, the coupling of flows of substrates: anti-porters and sym-porters, primary active transport systems, and the regulation and integration of transport systems.
More specifically, biogenic amines are transported through BBB by diffusion and it never occurs by carrier-mediated transport. Contrary to this, for uptake of other substances, uptake1 carrier involves that occuring at the luminal surface of BBB.
Further, metabolic fuels, monocarboxylic acids, ethanol, vitamins and neurotransmitters are carried by carrier-mediated transport because low lipid soluble biomolecules can traverse the blood brain barrier.
