Examples

• The sodium-glucose cotransports glucose into intestinal cells against its concentration gradient.
• Cotransports are essential for nutrient absorption in the small intestine.
• These cotransports couple the movement of sodium ions with the uptake of amino acids.
• The cell membrane contains many different cotransports that work simultaneously.
• Researchers studied how cotransports function at the molecular level using patch-clamp techniques.
