In his studies of alcoholic fermentation by yeast, louis pasteur noted that the sudden addition of oxygen (o2) to the previously anaerobic culture of fermentation grape juice resulted in a dramatic decrease in the rate of glucose consumption. this "pasteur effect" can be counteracted by the addition of 2,4-dinitrophenol (dnp), an uncoupler of oxidative phosphorylation.
