20. In аn insightful experiment perfоrmed in the 1960s, chlоrоplаsts were first soаked in an acidic solution at pH 4, so that the stroma and thylakoid space became acidified. They were then transferred to a basic solution (pH 8). This quickly increased the pH of the stroma to 8, while the thylakoid space temporarily remained at pH 4. A burst of ATP synthesis was observed, and the pH difference between the thylakoid and the stroma then disappeared. Explain your answers. (a) Explain why these conditions lead to ATP synthesis. (5 points) (b) Is light needed for the experiment to work? (5 points) (c) Would ATP be synthesized if the solutions were switched so that the first incubation is in the pH 8 solution and the second one in the pH 4 solution? (5 points)
