Import of Dietary Glucose from Intestines to Bloodstream




• Membranes have hydrophobic interiors. which resist the passage of hydrophilic compounds and ions. • However. transporter membrane proteins facilitate the passage of these molecules. • Passive transporters accelerate diffusion of molecules towards equilibrium (decrease a concentration gradient). They can be open pores or gated channels. • Active transporters use free energy to move molecules against equilibrium (increase a concentration gradient). • Types of transport: uniport (only one type of molecule is transported), antiport (molecules move in different directions), symport (molecules move in same direction)
