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.

• They generate glucose

• They capture light energy

• They produce carbon dioxide

What is the main difference between the light-dependent and light-independent reactions of photosynthesis?

• Light-dependent reactions produce ATP; light-independent do not

• Light-independent reactions occur at night; light-dependent during the day

• Light-dependent reactions require sunlight; light-independent do not

• Light-independent reactions produce oxygen; light-dependent do not
