Identify the person who was awarded noble prize for mapping of the pathway of carbon assimilation in photosynthesis. 

detailed solution

Correct option is C

Melvin Calvin along with J.A. Bassham studied reactions in green plants forming sugar and other substances from raw materials like carbon dioxide, water and minerals by labelling the carbon dioxide with C14. Calvin proposed that plants change light energy to chemical energy by transferring an electron in an organised array of pigment molecules and other substances. The mapping of the pathway of carbon assimilation in photosynthesis earned him Nobel Prize in 1961.
