E) formation of waste products in the form of O2
--the light reactions reduce NADP+ into NADPH2 and they don't deal with carbon (that's calvin cycle). They do break H2O down and the oxygen molecules are released as O2.
and
E) potential energy
--Molecule will flow down a concentration gradient, aka gas will diffuse from high pressure area to low pressure area.
