Question
In CAM plants, CO2 acceptor is
RuBP
PEP
OAA
PGA
Solution
B.
PEP
In CAM or Crassulacean Acid Metabolism plants, spatial separation of initial PEP carboxylase fixation and final Rubisco fixation of CO2, occur in the same cell, but at different times i.e. night and day, eg, Opuntia, pineapple, Vanilla.
PEP (Phosphoenol Pyruvic Acid) is the first acceptor of CO2 in CAM plants like C4 plants.
