Which of the following is the first compound that accepts carbon dioxide during dark reaction of photosynthesis?

Options

(a) NADP I
(b) RuBP
(c) ferredoxin
(d) cytochrome

Correct Answer:

RuBP

Explanation:

In C₃ plants, the carbon dioxide combines with ribulose-1-5-diphosphate (RuDP) (now called RuDP-Ribulose-1-5-bisphosphate) and gives rise to a 3-C compound, phosphoglyceric acid. It is first stable product of C₃ cycle. The process can be called as Calvin cycle.
