Which product of photolysis is needed for the continuation of the light reactions?

Here, NADP+ is the final electron acceptor, which becomes reduced to NADPH. Meanwhile, ATP is also formed. Therefore, these light reactions release oxygen as a waste product of photosynthesis, while ATP and NADPH are essential to the next step in photosynthesis, the dark reactions.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.
