1. ATP (adenosine triphosphate): ATP is the energy currency of cells. It's produced by the light-dependent reactions using the energy from sunlight to convert ADP (adenosine diphosphate) and inorganic phosphate into ATP.
2. NADPH (nicotinamide adenine dinucleotide phosphate): NADPH is a reducing agent that carries electrons. It's produced by the light-dependent reactions, capturing electrons from water molecules that have been split by sunlight.
These two molecules, ATP and NADPH, are then used in the Calvin cycle, the next stage of photosynthesis, to convert carbon dioxide into glucose, the sugar that provides energy for the plant.
