Which of the following experimental results does not support Mitchell's chemiosmosis theory?

• A. Electron transport in isolated mitochondria was shown to result in acidification of the medium
• B. Addition of dinitrophenol to isolated mitochondria was shown to inhibit electron transport, but had no effect on
• C. synthesis
• D. Addition of dinitrophenol to isolated mitochondria during electron transport was shown to inhibit acidification of the medium
• E. An artificial proton gradient across the inner mitochondrial membrane drives ATP synthesis in the absence of electron transport
