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 ATP synthesis
C. Addition of dinitrophenol to isolated mitochondria during electron transport was shown to inhibit acidification of the medium
D. An artificial proton gradient across the inner mitochondrial membrane drives ATP synthesis in the absence of electron transport
