Besides oxygen gas, what other two energy-containing molecules are produced by the light reaction?

NADH
ATP
e-

or is it
H20

i'm not quite sure.

i think that the answer is glucose and water vapor

sorry if im not too accurate, but i did biology last semester.. and i dont remember too much.. so heres what i think..

1) Light energy is absorbed by cholorphyll in the thylakoids drives the transfer of electrions from water to NADP+, forming NADPH. NADPH, an election acceptor, carries those electrons to the Calvin Cycle.
(i think NADPH might be one of those)

2) there are two types of photosystems in the  thylakoid membrane: Photosytem 1 and Photosystem 2
yea.. so.. here goes..
Photosystem II absorbs light energy and the energy is transferred to the primary electron acceptor. Electrons from photosystem II are replaced by splitting water, and O2 is released as a by-product. Electrons are passed along an electron transport chain to photosystem I and the energy is used to make ATP (note: as in cellular respiration, the ETC does not actually make any ATP directly).

so.. i think those two are atp and NADPH!

CO2 + 2 H2O + photons ? (CH2O)n + H2O + O2
   
carbon dioxide + water + light energy ? carbohydrate + oxygen + water

That's a gift.  If you want to be worth anything you really should read your text book.
