What Is the Balanced Chemical Equation for Photosynthesis?

By Staff WriterLast Updated Mar 31, 2020 8:40:05 AM ET

The balanced equation for photosynthesis is: 6CO2 + 6H2O + sunlight energy = C6H12O6 + 6O2 Photosynthesis can be represented using a chemical equation: Carbon dioxide + water + light energy gives a carbohydrate + oxygen.


Every living organism needs energy to survive, and photosynthesis is how plants capture the energy they require. During photosynthesis, energy from sunlight is used to convert water and carbon dioxide into chlorophyll, enzymes and sugars.

The sunlight energy is absorbed by chlorophyll and turned into chemical energy. The energy enables the production of glucose by the reaction between water and carbon dioxide. Oxygen is produced as a waste product. In most plants, photosynthesis occurs within the leaves.
