Question
In CAM plants, CO2 acceptor is
RuBP
PEP
OAA
PGA
Solution
B.
PEP
The process of photosynthesis in C4 plants and CAM (Crassulacean Acid Metabolism) is same. Instead of spatial separation of initial PEP, case fixation and final Rubisco fixation of CO2. Both the steps occur in same cell but at different times, night and day.
Eg, Opuntia, pinapple, Vanilla. PEP (Phosphoenol Pyruvate) is the first acceptor of CO2 in CAM plants.
