Suppose you were to add the uncoupler dinitrophenol (DNP) to a preparation of chloroplasts carrying out photosynthesis. What is the effect?
                     2,4-Dinitrophenol (DNP), C6H4N2O5, is an inhibitor of efficient energy (ATP) production in cells with mitochondria. It uncouples oxidative phosphorylation by carrying protons across the mitochondrial membrane, leading to a rapid consumption of energy without generation of ATP.  Dinitrophenols as a class of compounds, of which there are six members, do not occur naturally but are all manufactured compounds
