Expert Answer
Balance chemical equation for photosynthesis
6co2+ 6H2O + light energy >>> C6H12O6 + 6O2
6co2+ 6H2O + light energy >>> C6H12O6 + 6O2
During photosynthesis, carbon dioxide and water are used to synthesize sugars. It occurs with the help of the radiant energy of the sun which is absorbed by the chlorophyll of the green plants.
There are two main steps in photosynthesis are
Light Reaction- In this stage, light is absorbed in the presence of chlorophyll and water is splitted into hydrogen and oxygen.
Dark Reaction-In this stage, water and carbon dioxide are used to form carbohydrates. This is done with the help of a carbon acceptor - Ribulose Diphosphate (RuDP). Calvin cycle produces sugar molecules and regenerates the carbon acceptor which then enters another cycle. The hydrogen atoms set free during the light reaction are used to fix carbon dioxide. This stage is also called carbon assimilation.
