Predict how an amino acid with the chemical formula C4H7NO, is transported through the water-based blood stream to all body cells that need it. This amino acid O dissolves in the blood fluid and moves with the blood stream. O can only move through the blood stream with the help of a transport protein with hydrophobic amino acids on its outer surface. O can only move through the blood stream with the help of a transport protein with an internal pocket lined with hydrophobic amino acids. O can only move through the blood stream with the help of a transport protein with an internal pocket lined with hydrophilic amino acids.
