Here's a more detailed breakdown:

* Glucose (C6H12O6) is a simple sugar that serves as the primary energy source for plants and other organisms.

* Oxygen (O2) is released as a byproduct of photosynthesis and is essential for respiration in many organisms.

The overall chemical equation for photosynthesis is:

6CO2 + 6H2O + light energy → C6H12O6 + 6O2

This equation shows that carbon dioxide (CO2) and water (H2O) are used in the presence of light energy to produce glucose and oxygen.
