Answer #1

In the light reactions, light energy is used to oxidize water to oxygen

The electrons derived from this oxidation reaction in the light reactions are used to reduce NADP+ to NADPH

The calvin cycle oxidizes the light reactions product NADPH to NADP+

The electrons derived from this oxidation reaction in the calvin cycle are used to reduce CO2 to G3P
