Photosynthesis and Electron Flow Quiz

What is the final electron acceptor in non-cyclic electron flow?

• Oxygen

• NADP+

• Water

• ATP

How does chlorophyll contribute to the process of photosynthesis?

• It transports water.

• It releases oxygen.

• It absorbs light energy.

• It breaks down glucose.

What happens during photolysis in photosystem II?

• ATP is synthesized.

• Water is oxidized, releasing electrons.

• NADPH is converted to NADP+.

• Carbon dioxide is fixed.

Why would an increase in NADPH relative to NADP+ lead to more cyclic electron flow?

• Water is not split.

• NADP+ is not available to accept electrons.

• There is more ATP available.

• Oxygen is not released.

What is the effect of a CRR6 mutation on biomass accumulation?

• Biomass decreases due to less NADPH and ATP production.

• Biomass remains unchanged.

• Biomass increases due to more ATP production.

• Biomass increases due to more carbon fixation.
