Which products formed during the light reaction of photosynthesis are used to drive the dark reaction ?

Explanation

**Step-by-Step Solution:**

1. **Understanding Photosynthesis**: Photosynthesis consists of two main stages: the light reactions and the dark reactions (Calvin cycle). The light reactions occur in the thylakoid membranes of the chloroplasts and require light energy.

2. **Products of Light Reactions**: During the light reactions, two key products are generated:
- **ATP (Adenosine Triphosphate)**: This molecule serves as an energy currency in cells.
- **NADPH (Nicotinamide Adenine Dinucleotide Phosphate)**: This molecule acts as a reducing agent, providing the necessary electrons for the reactions in the dark phase.
