A) Benson and Calvin
B) Hill and Calvin
C) Hatch and Slack
D) Emerson and Arnold
Correct Answer: D
Solution :
Emerson and Arnold (1932) established light and dark phases in photosynthesis with the help of flashing light and Ermerson concluded two distinct photochemical process in light reaction of photosynthesis. Calvin traced the path of carbon fixation by using \[({{\,}^{14}}C{{O}_{2}})\] and gave\[{{\text{C}}_{\text{3}}}\]cycle also known as Calvin cycle. Hill (1937) performed that \[{{\text{O}}_{\text{2}}}\] evolved in light reaction of photosynthesis in absence of \[\text{C}{{\text{O}}_{2}}.\]Hatch and Slack (1965) discovered supplementory mechanism of \[\text{C}{{\text{O}}_{\text{2}}}\]fixation called \[{{\text{C}}_{4}}\] pathway in certain tropical plants.
