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.

What happens to the O₂ created in the light phase?

• Is transferred to the Calvin Cycle

• Donates its electrons to the Chlorophyll molecules

• Provides a carbon to form the unstable 6-carbon molecule

• Diffuses out through the stoma
