The equation for photosynthesis is: 6CO2 + 12H2O → C6H12O6 + 6O2 + 6H2O

This could be simplified to (and is usually seen as): 6CO2 + 6H2O → C6H12O6 + 6O2.

From the equations above, it could be seen that sunlight is not a reactant in photosynthesis. Reactants are substances that takes part in and undergoes change during a reaction. Sunlight does not; hence sunlight is not a reactant in photosynthesis.

No its a product. Produced via photolysis of water 2h20 -- O2 + 4h+ 4e- . Electrons reduce chlorophyll after it has been oxidised when it donates electrons to the electron transport chain.

What is the water equation?

In order to have a balanced equation, adding the reactant H2 And O2 (H2+O2) have to come out equal on the product side and the reactant side. This would look like H2+O2 = H2O2

How do photosynthesis and respiration take part in O2 cycle?

During photosynthesis O2 is released by the photolysis of water whereas in respiration O2 is consumed in the breakdown of substrate(reserve food).In simple words , Photosynthesis release O2 while respiration requires O2.
