6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂
This means:
* 6 molecules of carbon dioxide (CO₂) + 6 molecules of water (H₂O) + light energy are used to produce
* 1 molecule of glucose (C₆H₁₂O₆) + 6 molecules of oxygen (O₂)
Here's a breakdown:
* Carbon dioxide (CO₂): The source of carbon for building glucose.
* Water (H₂O): The source of hydrogen and electrons for glucose, and the oxygen atoms released as a byproduct.
* Light energy: Provides the energy required for the reaction.
* Glucose (C₆H₁₂O₆): A sugar molecule that is the primary energy source for plants and other organisms.
* Oxygen (O₂): A byproduct of photosynthesis that is released into the atmosphere.
This reaction is actually a simplified representation of a complex process that occurs in two stages:
1. Light-dependent reactions: Capture light energy and convert it into chemical energy in the form of ATP and NADPH.
2. Light-independent reactions (Calvin cycle): Use the ATP and NADPH produced in the light-dependent reactions to convert CO₂ into glucose.
