What Is the Photosynthesis Equation?

BiologyChemistry

Quick Answer

6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂ — carbon dioxide and water are converted into glucose and oxygen using sunlight.

The Full Story

Photosynthesis is the process by which plants, algae, and cyanobacteria convert light energy into chemical energy stored in glucose. It occurs in two stages within chloroplasts: the light-dependent reactions (in the thylakoid membranes) capture solar energy to split water molecules, producing oxygen, ATP, and NADPH; the light-independent reactions (the Calvin cycle, in the stroma) use that ATP and NADPH to fix CO₂ into glucose. The overall equation — 6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂ — is among the most important in biology, as it underpins nearly all food chains and produces the oxygen we breathe.

Key Facts

1.Photosynthesis produces about 130 terawatts of chemical energy annually — roughly six times total human energy consumption.
2.Chlorophyll reflects green wavelengths and absorbs red and blue, which is why most plants appear green.
3.Some bacteria perform anoxygenic photosynthesis, using hydrogen sulfide instead of water and producing no oxygen.
