Which of the following occurs during light reactions?

All of the following occur during the light reactions of photosynthesis:
- Absorbs light to produce ATP: The light reactions use light energy to produce ATP, which is the energy currency of the cell.
- Produces nicotinamide adenine dinucleotide phosphates (NADPH): The light reactions also produce NADPH, which is a reducing agent that is used to convert carbon dioxide into glucose in the Calvin cycle.
- Water molecules are split & transferred to the electron transport chain: Water molecules are split in the light reactions to produce oxygen and hydrogen. The hydrogen atoms are then transferred to the electron transport chain, which is a series of proteins that generate ATP.
