Which is the correct chemical equation for photosynthesis?

Carbon dioxide + electron donor + light energy - > carbohydrate + oxidized electron donor + water or CO2 + 2H2A + photons - > [CH2O] + 2A + H2O

Symbol equation:

CO2 + H2O - > C6H12O6 + O2

(the numbers should be smaller and towards the bottom right in written form)

Word equation:

Carbon dioxide + Water - > Glucose + Oxygen

This reaction requires light energy so where the arrow is, although not an actual element, light energy should be placed nearby if possible
