Which equation represents photosynthesis?

The process of photosynthesis is represented by the equation that shows how plants convert carbon dioxide and water into glucose and oxygen, using light energy. In this context, the reaction can be summarized as:

6CO2 (carbon dioxide) + 6H2O (water) + light energy → C6H12O6 (glucose) + 6O2 (oxygen).

This equation captures the essence of photosynthesis by illustrating that six molecules of carbon dioxide react with six molecules of water to produce one molecule of glucose and six molecules of oxygen. The inclusion of "ATP energy" in options suggests a misunderstanding since while ATP is involved in the energy transfer during photosynthesis, it is not a product of the photosynthesis equation itself. Instead, glucose acts as the energy-storing compound produced in this process.

Therefore, the chosen equation accurately reflects the conversion of inorganic molecules into organic molecules with the release of oxygen as a byproduct, which is fundamental to the process of photosynthesis.
