Question

2,4-Dinitrophenol (DNP) is a proton ionophore. This means that DNP allows the passage of protons from one side of a biological membrane to the other. In the body, DNP is a poison that can result in fatal hyperthermia. What is happening in a case like this? Check all that apply. DNP allows protons to bypass ATP synthase as the protons move down the concentration gradient DNP couples the proton motive force to ATP synthesis DNP results in the conversion of energy of the proton motive force into heat energy DNP results in thermogenesis rather than ATP synthesis DNP uncouples the proton gradient generated by the electron transport chain from the synthesis of ATP by ATP synthase
