Abstract
2,4-Dinitrophenol, while increasing respiration, inhibits the accumulation of ions by carrot cells. Further investigation is necessary to detn. whether the inhibition is due to a direct effect of the dinitrophenol on the mechanism or whether the dinitrophenol on the mechanism or whether the dinitrophenol indirectly prevents the mechanism from operating by causing some disorganization within the cell, possibly in the mitochondria. If the assumption that dinitrophenol inhibits phosphate transfers is justifiable, hypotheses of salt accumulation might require modification to allow for the participation of energy-rich phosphate. This would suggest that the Lundegardh mechanism may be a part of a more complex mechanism.
