A) Arnon
B) Hill
C) Blackman
D) None of these
Correct Answer: D
Solution :
Robert Emerson indicated the existence of two pigment systems participating in light reaction. One pigment system has the affinity for light of higher wavelength (red light above 660 nm) and the other has the affinity for light of lower wavelength, (less than 680 nm). Both the pigment system actively assist each other. Robert Hill demonstrated photolysis of water in light reaction. Arnon discovered the mechanism of photo-phosphorylation in chloroplasts and Blackman reported photosynthesis as a photochemical reaction.
