Photosynthesis is a natural process by which plants and trees pull carbon dioxide from the air to make carbohydrates as food for themselves. Light is necessary for the reaction to take place. Photosynthesis can be written as a chemical equation. The overall equation is as follows:
6CO2 + 6H2O −−−−−> C6H12O6 + 6O2
CO2 is carbon dioxide, H2O is water.
Light energy is required.
C6H12O6 is glucose.
O2 is oxygen.
As light energy (in the form of photons) reaches a plant, chlorophyll molecules forming a light-harvesting complex absorb that energy, thus exciting electrons. These electrons move along an electron transport chain, eventually transferring their ...
