The diagram below represents an experiment which was carried out with isolated chloroplasts. The chloroplasts were first made acidic by soaking them in a solution at pH at 4. After the thylakoid space reached pH 4, the chloroplasts were transferred to a basic solution at pH 8. The chloroplasts are then placed in the dark. Which of these compounds (ATP, NADPH, H+, G3P) would you expect to be produced? Explain.
