Question

In Calvin cycle, Rubisco incorporates CO\textsubscript{2 into ribulose 1,5 bisphosphate which rapidly splits into:}

• A. Glyceraldehyde 3-phosphate
• B. 2,3 phosphoglyceric acid
• C. 3 phosphoglycerate
• D. 1,3 diphosphoglycerate

Hint:

RuBP + CO\textsubscript{2} → 2 × 3-PGA in the first stable step of the Calvin cycle.

Answer 1

The Correct Option is C

In the Calvin cycle, Rubisco catalyzes the carboxylation of ribulose 1,5
bisphosphate (RuBP) with CO\textsubscript{2}, forming two molecules of 3
phosphoglycerate (3
PGA).
