. Photosynthesis is a/an
A: Reduction reaction.
B: Oxidation reaction.
C: Oxidation-reduction reaction.
D: None of the above.
The absorption of light energy and its conversion into chemical potential is known as photosynthesis.
Photosynthetic reactions include-
6CO2 + 12H2O→C6H12O6 +6O2+6H2O
In the above reaction, carbon is reduced to glucose in the presence of sunlight and chlorophyll whereas water is oxidized to oxygen.
Hence, photosynthesis is an oxidation-reduction reaction.
So, The correct option is C.
