Question

sample response: 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.
what did you include in your response? check all that apply.
electrons from psii would not be transported to psi.
psi would have no electrons to transport to ferredoxin.
ferredoxin would have no electrons to transport to nadp+.
nadph would not be produced.
the light - independent reaction of photosynthesis would be affected.

Explanation:

The sample response clearly mentions that electrons from PSII would not be transported to PSI, which is the first option. It also states that ferredoxin would have no electrons to transfer to NADP⁺ (third option), NADPH would not be produced (fourth option), and the light - independent reaction of photosynthesis would be affected (fifth option). The second option is incorrect as the sample response says electrons from PSII are not transferred to PSI, not that PSI has no electrons to transport to ferredoxin.

Answer:

Electrons from PSII would not be transported to PSI, Ferredoxin would have no electrons to transport to NADP⁺, NADPH would not be produced, The light - independent reaction of photosynthesis would be affected.
