the uncoupler dinitrophenol (dnp) prevents atp synthesis while allowing electron transport to proceed because question 9 options: dnp binds to the atp synthase and acts as an inhibitor of the enzyme. dnp prevents the buildup of a proton gradient by altering the electron transfer complexes such that they no longer pump protons. dnp can transport protons across the membrane, dissipating the proton gradient. dnp transports protons out of the mitochondria after they are pumped out of the matrix.
