Respuesta :

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
