Which of the following best describes the relationship between light and dark reactions in photosynthesis?

• Light reactions produce glucose, and dark reactions produce oxygen.

• Light reactions produce energy carriers, and dark reactions use them to fix carbon dioxide.

• Light reactions occur at night, and dark reactions occur during the day.

• Light reactions use carbon dioxide, and dark reactions use water.

How do the light and dark reactions of photosynthesis complement each other?

• Light reactions produce oxygen, and dark reactions produce carbon dioxide.

• Light reactions provide energy carriers for dark reactions to synthesize glucose.

• Light reactions occur in the roots, and dark reactions occur in the leaves.

• Light reactions use glucose, and dark reactions use oxygen.

How does water split in the light dependent reaction?

• Into O2 that goes to the calvin cycle and the Hydrogens are released to the atmosphere

• Into 6O2 that is released into the atmosphere and the H+ get picked up by Atp. 

• Into 6O2 that is released into the atmosphere and the H+ gets picked up by NADP+ to carry to the light dependent cycle. 

• Into 6O2 that is released into the atmosphere and the H+ gets picked up by NADP+ to carry to the H+ to the Calvin cycle and to help create ATP.

• Generation of ATP and NADPH

• Absorption of water
