What Is the Overall Reaction for Photosynthesis?

The chemical reaction for the completion of photosynthesis is 6CO2 + H20 + light energy –> C6H12O6 + 6O2. The reaction utilizes carbon dioxide from the atmosphere, water from the plant and light from the sun to produce glucose for the plant and oxygen for the atmosphere.

Photosynthesis allows plants to create glucose in order to sustain life. Plants utilize glucose as a source of energy and nutrition. The overall reaction of photosynthesis is completed in the chloroplasts of the plant cells with the pigment chlorophyll. The reaction is completed in two parts: one part begins and ends during the day when the sun is out and the last part finishes at night when the sun goes down.
