Question
CO2 acceptor in C3 cycle is
OAA
RuBP
PEP
Malic acid
Solution
B.
RuBP
Primary carbon dioxide acceptor in C4 plant is phosphoenol pyruvic acid,it contains 3 carbon atoms. in C3 plants ribulose 1,5 bisphosphate (RUBP) is the primary CO2 acceptor. It is a 5 carbon compound. In C4 plants phospho enol pyruvate (PEP) is primary CO2 acceptor.
