The first stable compound formed during C₃ cycle is

Options

(a) glycolate
(b) formaldehyde
(c) phosphoglyceric acid
(d) phosphoglyceraldehyde

Correct Answer:

phosphoglyceric acid

Explanation:

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