Experiments 1, 2 and 3 were conducted wherein synthetic vesicles containig `F_(0)`-`F_(1)` ATP synthase were prepared and incubated overnight in a tube. Subsequently the vesicles were transferred to another tube which also contained ADP and Pi (inorganic phosphate)
A) A proton gradient across the vesicular membrance will be present in both experiments 1 and 2 at the time of transfer
B) As a consequences of the proton gradient, ATP will be synthesized in both experiments 1 and 2
C) ATP will be synthesized in experiment 3 because `F_(0)-F_(1)` ATP synthesis has the inhernt property to catalyse the synthesis of ATP from ADP and Pi
D) ATP will be synthesized in experiment 2 because the proton has to flow out of the vesicles through the `F_(0)-F_(1)`ATP synthase for ATP synthesis
