Detailed Solution for VITEEE Biology Test - 6 - Question 26

Bacteria use radiant energy between 870 to 1020 nm of the infrared region instead of visible light for photosynthesis. Thus the reaction center is B-890 which is the only pigment system present but both the cyclic and noncyclic reaction takes place in it. It utilizes hydrogen sulfide, thiosulphate as reducing power and does not evolve oxygen and maximum absorption is between 600 to 700 nm. Thus, the correct answer is option B.
