In bacterial photosynthesis,which of the following is present?

$A$ student performed an experiment on photosynthesis as follows: They took soda water in a glass tumbler and added chlorophyll to it. They placed the tumbler in sunlight,expecting that they had provided all the necessary components for photosynthesis (i.e.,$CO_2$,$H_2O$,chlorophyll,and light). What do you think will happen after a few hours of exposure to sunlight?

Choose the incorrect statement with respect to photosynthesis.

Assertion: Six molecules of $CO_2$ and twelve molecules of $NADPH + H^+$ and $18\, ATP$ are used to form one hexose molecule.
Reason: Light reaction results in the formation of $ATP$ and $NADPH_2$.

For the process of photosynthesis,all except one of the following items are essential. Point out the exception.
