We develop a rapid "stroboscopic" fluorescence induction method, using the fast repetition rate fluorometry (FRRF) technique, to measure changes in the quantum yield of light emission from chlorophyll in oxygenic photosynthesis arising from competition with primary photochemical charge separation (P680* ➔ P680+QA-). This method determines the transit times of electrons that pass through PSII during the successive steps in the catalytic cycle of water oxidation/O2 formation (S states) and plastoquinone reduction in any oxygenic phototr
