Answer:
Photosynthesis takes place in two sequential stages; Light-dependent Reactions and Calvin Cycle. The Light-dependent Reaction uses water and light. Light provides the energy needed to break apart the water molecules. This process will make oxygen and hydrogen ions. The hydrogen ions are used to make ATP (Adenosine Triphosphate) while the Calvin Cycle uses carbon from the carbon dioxide, energy from the ATP, and high-energy electrons and hydrogen ions from the NADPH (nicotinamide adenine dinucleotide phosphate hydrogen). The cycle's output is an energy-rich sugar molecule. The plant cell uses G3P (glyceraldehyde-3-phosphate) as the raw material to make glucose and other organic molecules it needs.
