In dark conditions, this molecule binds to RuBisCO, preventing it from participating in chemical reactions. As the amount of light present increases, CA1P levels decrease, freeing RuBisCO's reactive ends, allowing more of the molecules to participate in chemical reactions. It is removed from Rubisco's active sites through the action of Rubisco activase (Rca)Bhat Javaid Y.
