<prompt> Dinitrophenol causes:Inhibition of ATP synthaseInhibition of electron transportUncoupling of oxidation and phosphorylationAccumulation of ATP  <response>: Ans. C. Uncoupling of oxidation and phosphorylationDinitrophenol uncouples oxidation and phosphorylation in the respiratory chain. The hydrogen ions reenter the mitochondrial matrix without ATP synthesis. The energy is released as heat.
