WebPhotosynthesis is a chemical process in which light energy from the sun drives a series of chemical reactions between carbon dioxide and water, forming glucose (a simple sugar) and oxygen as end products. The overall process can be expressed as follows: carbon dioxide + water + light energy → glucose + oxygen. The reaction requires ...

Chemically, photosynthesis is the reverse reaction of respiration. Compare the two reactions: If respiration (reaction 1) is the complete oxidation of glucose to H2O and CO2, then photosynthesis (reaction 2) is the reduction of CO2 using electrons from H2O. Photosynthesis is thus an endergonic reaction.
