WebAug 20, 1996 · Correct! Dinitrophenol (DNP) is an uncoupler, or has the ability to separate the flow of electrons and the pumping of H + ions for ATP synthesis. This means that the … WebAbstract. Glucosamine induced insulin resistance in 3T3-L1 adipocytes, which was associated with a 15% decrease in cellular ATP content. To study the role of ATP depletion in insulin resistance, we employed sodium azide (NaN3) and dinitrophenol (DNP), which affect mitochondrial oxidative phosphorylation, to achieve a similar 15% ATP depletion.
