Photosynthesis Equation

Understand the simple chemical equation that describes the process of Photosynthesis.

What is the Photosynthesis Equation?

Photosynthesis is the process by which plants use the energy from sunlight to produce sugar, which in simpler words is the 'fuel' used by all living things. The photosynthesis equation is a chemical representation of the process of photosynthesis which takes place in the chloroplasts. Plants take in carbon dioxide and water to produce glucose (a sugar) and oxygen. The following is the chemical equation, that expalins this process:


Carbon dioxide + water produces -> glucose + oxygen

In chemical language, this is written as,


6CO­2 + 6H2O produces -> C6H12O6 + 6O2

The above chemical equation is read as,
Six molecules of carbon dioxide plus six molecules of water, produce one molecule of sugar and six molecules of oxygen.


What does the Equation mean:
Photosynthesis occurs in two stages. In the first stage, light-dependent reactions capture energy of light and use it to make the energy-storage molecules called ATP and NADPH. During the second stage, the reactions then use these products to capture and reduce carbon dioxide.


The Products of Photosynthesis:
The final product of photosynthesis which is glucose is stored in the complex molecular structure of the plant cells. Oxygen produced as a byproduct is released to the surrounding which is used in respiration by living organisms. In addition to oxygen supply, the glucose synthesized by means of photosynthesis is source of energy for living organisms and is circulated in the food chain. Thus, plants are crucial for balancing the atmospheric air composition and supporting the aerobic ecosystem in every way.


It is interesting to notice that when we burn wood, we’re basically reversing the chemical formulae of photosynthesis that was just explained. The carbohydrate is breaks down and carbon dioxide gas, water and energy are produced. In a more real sense, first sunlight is captured in the carbohydrate, which is then stored in the plant for a while. When the process of burning starts, the sunlight's energy would be released again.
