Question

Quizplus · Accepted Answer

The known mechanisms of activation of rubisco or of other enzymes of the Calvin cycle during illumination include increased stromal pH, light-driven entry of Mg²⁺ into the stroma, reduction of a disulfide bridge by thioredoxin. However, phosphorylation by cAMP-dependent protein kinase is not one of the known mechanisms. Additionally, phosphorylation of phosphoenolpyruvate carboxylase is a mechanism of activation in C4 plants, but not in the Calvin cycle.
