<prompt> Which of the following is an effect of dinitrophenol on oxidative phosphorylationInhibition of cytochrome bBlockade of both electron transport and ATP synthesisInhibition of ATP synthesis with normal electron transportInhibition of electron transport but not ATP synthesis  <response>: Inhibition of ATP synthesisDinitrophenol is an uncoupler.Uncouplers cause uncoupling of oxidation and phosphorylation, i.e. they allow electrons transport to proceed without ATP synthesis.
