The carbon dioxide acceptor in Calvin cycle/C3-plants is
A. Phospho-enol pyruvate (PEP)
B. Ribulose 1, 5-diphosphate (RuBP)
C. Phosphoglyceric acid (PGA)
D. Ribulose monophosphate (RMP)
Answer: Option B
Solution(By Examveda Team)
The carbon dioxide acceptor in Calvin cycle/C3-plants is Ribulose 1, 5-diphosphate (RuBP).Ribulose 1,5-bisphosphate (RuBP) is an organic substance that is involved in photosynthesis, notably as the principal CO2 acceptor in plants. It is a colourless anion, a double phosphate ester of the ketopentose (ketone-containing sugar with five carbon atoms) called ribulose.
The enzyme ribulose-1,5-bisphosphate carboxylase-oxygenase (rubisco) catalyzes the reaction between RuBP and carbon dioxide.
