Question

The carbon dioxide acceptor in Calvin cycle / C3-plants is

(a) Phosphoenol Pyruvate (PEP)

(b) Ribulose 1,5-Diphosphate (RuDP)

(c) Phosphoglyceric Acid (PGA)

(d) Ribulose Monophosphate (RMP)

Answer 1

Correct option**(b) Ribulose 1,5-Diphosphate (RuDP)**

Explanation :

In C3 -plants,CO2 combines with riboluse biohosphate (acceptor molecule) in the presence of RuBisCO ( RuBP carboxylase) and from PGA (first stable product).
