Plant Structure Which of the following experimental results does not support Mitchell's chemiosmosis theory? 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 An artificial proton gradient across the inner mitochondrial membrane drives ATP synthesis in the absence of electron transport Addition of dinitrophenol to isolated mitochondria was shown to inhibit electron transport, but had no effect on ATP synthesis 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 An artificial proton gradient across the inner mitochondrial membrane drives ATP synthesis in the absence of electron transport Addition of dinitrophenol to isolated mitochondria was shown to inhibit electron transport, but had no effect on ATP synthesis ANSWER DOWNLOAD EXAMIANS APP
Plant Structure The mitochondria were known in the nineteenth century to be osmotically active on the basis of evidence that the mitochondrial matrix is hypertonic to the cellular cytoplasm the mitochondrial matrix is hypotonic to the cellular cytoplasm mitochondria were derived from a symbiotic bacterium mitochondria are surrounded by a semi permeable membrane the mitochondrial matrix is hypertonic to the cellular cytoplasm the mitochondrial matrix is hypotonic to the cellular cytoplasm mitochondria were derived from a symbiotic bacterium mitochondria are surrounded by a semi permeable membrane ANSWER DOWNLOAD EXAMIANS APP
