1. ATP (Adenosine triphosphate): This is the energy currency of cells. It's a high-energy molecule used to power various cellular processes.
2. NADPH (Nicotinamide adenine dinucleotide phosphate): This is a reducing agent, carrying high-energy electrons that are used to power the Calvin cycle (the dark reactions).
3. Oxygen (O2): This is a byproduct of the light reactions. It's produced when water molecules are split to provide the electrons for the electron transport chain.
