Q. The first stable product of Calvin cycle is

AIIMSAIIMS 2010Photosynthesis in Higher Plants

Solution:

Calvin pathway occurs in all photosynthetic plants which is CO2 fixation cycle. Carbon dioxide combines with ribulose‐1, 5‐biphosphate (RuBp) to produce a transient intermediate compound. The intermediate compound splits up immediately in the presence of water to form the two molecules of 3‐phosphoglycerate or 3‐PGA. It is the first stable product of photosynthesis.
