Answer:
If the electron transport system did not work, electrons from PSII would not be transferred to PSI. Ferredoxin would then have no electrons to transfer to NADP+ so NADPH would not be produced. This would also affect the light-independent reaction of photosynthesis because NADPH is needed in this reaction.
