What is the role of molecular oxygen in photosynthesis?

a.

It is a byproduct from the splitting of water during the light reactions, and is excreted from the plant.
b.

It is taken up by plants and is used for the generation of ATP during photophosphorylation in the light reactions.
c.

It is the source of the oxygen atoms in glucose and other carbohydrates formed during the Calvin cycle.
d.

It is the final electron acceptor in the electron transport chain of the light reactions and is used to make water.

What are the products of the light reactions?

a.

glucose and NADPH
b.

NADPH and ATP
c.
