Why photosynthesis is a type of redox reaction |
|
Answer» Photosynthesis is a type of redox reaction because oxidation and reduction both are takes place in photosynthesis \tRedox reaction (oxidation-reduction reactions) are marked by the transfer of electrons. During oxidation, a substance tends to lose its electrons whereas, during reduction, a substance tends to gain electrons.\t\xa0Photosynthesis is a process in which plants containing chlorophyll convert the carbon dioxide into sugars in the presence of sunlight by a set of redox reactions.\xa0\tCalvin cycle represents a set of reactions which are used to remove electrons from water which are then used to turn carbon dioxide into organic compounds.\tRedox reactions during photosynthesis :It involves two major steps -\xa0\tThe first step is the oxidation in oxygen in water molecule in the presence of light2H2\u200bO → O2\u200b + 4H+The second step is the reduction step where hydrogen ions reduce the carbon in carbondioxide4H+ + CO2\u200b → (CH2\u200bO) + H2\u200b0The net reaction isCO2\u200b + H2\u200bO → (CH2\u200bO) + H2\u200bO |
