Plant Structure Which of the following experimental results does not support Mitchell's chemiosmosis theory? Electron transport in isolated mitochondria was shown to result in acidification of the medium Addition of dinitrophenol to isolated mitochondria was shown to inhibit electron transport, but had no effect on ATP synthesis An artificial proton gradient across the inner mitochondrial membrane drives ATP synthesis in the absence of electron transport Addition of dinitrophenol to isolated mitochondria during electron transport was shown to inhibit acidification of the medium Electron transport in isolated mitochondria was shown to result in acidification of the medium Addition of dinitrophenol to isolated mitochondria was shown to inhibit electron transport, but had no effect on ATP synthesis An artificial proton gradient across the inner mitochondrial membrane drives ATP synthesis in the absence of electron transport Addition of dinitrophenol to isolated mitochondria during electron transport was shown to inhibit acidification of the medium ANSWER DOWNLOAD EXAMIANS APP

Plant Structure Why do some redox reactions in cells result in the transfer of electrons from a reductant with a higher standard redox potential to an oxidant with a lower standard redox potential? None of these The rules governing oxidation and reduction apply only in vitro, and not in vivo Redox potentials are defined under standard conditions, and cellular conditions are typically not standard conditions Electrons always go from reductants with high redox potentials to oxidants with low redox potentials None of these The rules governing oxidation and reduction apply only in vitro, and not in vivo Redox potentials are defined under standard conditions, and cellular conditions are typically not standard conditions Electrons always go from reductants with high redox potentials to oxidants with low redox potentials ANSWER DOWNLOAD EXAMIANS APP
