Actually glucose is not a primary product of photosynthesis, G3P, aka PGA is the product of the Calvin cycle. G3P is a 3-Carbon sugar that can be used to make glucose, but it is also used to make amino acids and other organic molecules. The majority of G3P is turned into glucose and glucose is then turned to starch. A by-product of PS is oxygen.

The primary product of photosynthesis is glucose (C₆H₁₂O₆), which serves as the energy source for the plant and forms the basis of the food chain.
6CO2 + 6H2O (light energy, chlorophyll) = C6H12O6 (glucose) + 6O2 (oxygen)
Here, oxygen (O₂) is the main by-product released into the environment, which benefits other organisms for respiration.
