<Dd> carbon dioxide + water + light energy → carbohydrate + oxygen + water </Dd> <P> This equation emphasizes that water is both a reactant in the light - dependent reaction and a product of the light - independent reaction, but canceling n water molecules from each side gives the net equation: </P> <Dl> <Dd> CO + H O + photons → (CH O) + O </Dd> <Dd> carbon dioxide + water + light energy → carbohydrate + oxygen </Dd> </Dl> <Dd> CO + H O + photons → (CH O) + O </Dd>
