The CO₂ acceptor in the Calvin cycle is ______?

The CO₂ acceptor in the Calvin cycle is ______?

Explanation

The actual CO₂ acceptor in the Calvin cycle is ribulose-1,5-bisphosphate (RuBP), a phosphorylated form of ribulose.

RuBP combines with CO₂ in a reaction catalyzed by Rubisco, initiating the Calvin cycle.
