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

* Oxygen (O2): This gas is released as a byproduct of photosynthesis and is essential for respiration in most living organisms.

The overall equation for photosynthesis is:

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

This means that six molecules of carbon dioxide (CO2) and six molecules of water (H2O) are combined in the presence of light energy to produce one molecule of glucose (C6H12O6) and six molecules of oxygen (O2).
