Following are some facts regarding spatial separation of PSI and PSII. Which one would be INCORRECT?

#Unit 6. System Physiology – Plant

PSII reaction centres feed reducing equivalents into a common intermediate pool of soluble electron carriers while The PSI reaction centres remove the reducing equivalents from the common pool
Most commonly, the ratio of PSII to PSI is about 1.5:1, but it can change when plants are grown in different light conditions
Most measurements of the relative quantities of photosystems I and II have shown that there is an excess of photosystem II in chloroplasts
Separation implies that one or more of the electron carriers that function between the photosystems diffuses from the grana region of the membrane to the stroma region, where electrons are delivered to photosystem II
