Process of Light-dependent Reactions
- Chlorophyll takes in solar energy and transfers it to high-energy electrons. These electrons are passed through a series of proteins called the electron transport chain.
- NADP+ molecules accept high-energy electrons. With the electrons, NADP+ molecules form NADPH. NADPH carries the electrons and their energy to the next phase, the light-independent reactions.
- Oxygen gas is released and ATP molecules are formed. The next phase requires these ATP molecules.
