Ion movement in cell membranes is essential for all important functions – nutrient uptake, waste disposal and energy conservation. EU researchers have looked at movement at the molecular level in cell respiration.
Recent discoveries about the antiporter system in cell membranes have sparked interest in exactly how different ions are transported in different directions at the same time. Recent data indicates that hydrogen and sodium ions are exchanged across the plasma membrane by an antiporter protein complex.
