To determine the end products of the light-dependent reactions of photosynthesis, we need to understand the process involved in these reactions.
1. Light-dependent reactions occur in the thylakoid membranes of the chloroplasts. These reactions capture light energy to synthesize molecules that will be used in the Calvin cycle (light-independent reactions).
2. In these reactions, the energy from sunlight is absorbed by chlorophyll and other pigments. This energy is used to drive the splitting of water molecules (H₂O), which releases oxygen (O₂) as a byproduct.
3. The light energy also helps in converting ADP and inorganic phosphate (Pi) to ATP through the process called photophosphorylation.
4. Additionally, the electrons released from the water molecule are transferred to NADP+ to form NADPH.
Therefore, the end products of the light-dependent reactions of photosynthesis are ATP, NADPH, and O₂.
The correct option is:
ATP, NADPH, and [tex]$O _2$[/tex]
