The acceptor of CO2 in C3 -plant is
A. 3 phosphoglyaric acid
B. Phosphoenol pyruvic acid
C. 1, 5 ribulose biphosphate
D. Xylulose biphosphate
Answer: Option C
Solution(By Examveda Team)
The acceptor of CO2 in the C3 -the plant is 1, 5 ribulose biphosphate (RUBP a 5 Carbon compound).The enzyme RuBisCO catalyzes the carboxylation of ribulose-1,5-bisphosphate, RuBP, a 5-carbon compound, by carbon dioxide (a total of 6 carbons) in a two-step reaction.
The product of the first step is an enediol-enzyme complex that can capture CO2 or O2. Thus, enediol-enzyme complex is the real carboxylase/oxygenase.
