Following is a diagram of the first experiment demonstrating that pH gradient and proton flow is related to ADP -> ATP conversion. F0F1 units on membrane vesicles are isolated. Then it was soaked in a solution with pH A. After the pH inside the vesicle reaches pH A, the solution is changed to pH B. The pH difference between inside and outside drives ATP synthase to convert ADP to ATP. One of the solutions has pH 4.0, the other pH 8.0. Which is pH A and which is pH B?

The higher the pH on the outside, the more ATP is produced. Thus, it has to be more acidic outside (pH 4.0) the cell in order for more ATP to be produced.
