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

* Oxygen (O2): This gas is released into the atmosphere as a byproduct of photosynthesis. It is essential for the respiration of most living organisms.

So, 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).
