WebJan 3, 2024 · 7.4: Photosynthesis. 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.
