What causes carboxylation of a critical lysine residue that coordinates Mg²⁺ in the rubisco active site to occur?

Question

Quizplus · Accepted Answer

The carboxylation of the critical lysine residue in the rubisco active site is promoted by a high pH, which occurs when the light reactions of photosynthesis are highly active. This is because the light reactions generate ATP and NADPH, leading to proton consumption in the Calvin cycle and an increase in stromal pH.
