WebMay 31, 2024 · How does DNP poisoning affect the electron transport chain? After DNP poisoning, the electron transport chain can no longer form a proton gradient, and ATP synthase can no longer make ATP. Since ATP cannot be formed, the energy from electron transport is lost as heat. WebDNP can also cause a number of other side effects such as: nausea. vomiting. sweating. dizziness. headache. elevated heart rate. How does DNP affect your body’s function? DNP decreases the formation of high-energy phosphate bonds in mitochondria and at the same time stimulates systemic oxygen consumption [23].
