Prior to CO2 fixation, Activation of RUBISCO/Carbamylation of RUBISCO takes place

1. Two protons are released. 

2. Binding of CO2 molecule on NH2 group

3. Binding of Mg2+ concentration upon illumination

The signals flow from the chloroplast to the nucleus is retrograde:

plastidial ferrochelatase I catalyzes the synthesis of heme, which in turn regulates the expression of nuclear encoded, chloroplast‐targeted proteins in greening leaves.
