The path of electron transfer in photosynthesis process via photosystem − I and photosystem − II is to be explained. Concept Introduction: Oxidation is the addition of an electronegative element or the removal of an electropositive element in a chemical reaction . Reduction is the addition of an electropositive element or the removal of an electronegative element in a chemical reaction. The chemical reaction in which oxidation process and reduction process takes place and reduction take place simultaneously is called a redox reaction . The chemical reaction that takes place during photosynthesis is shown as follows: 6CO 2 + 6 H 2 O → C 6 H 12 O 6 + 6O 2 During the light reaction, the reduction of NADP + to NADPH , accompanied by the oxidation of water results in the formation of oxygen during photosynthesis.
