Which of the following statements is INCORRECT?

#XL - R Botany

Rubisco activase is an enzyme which regulates rubisco and uses ATP for the regulation of Rubisco
In the rubisco-activase–mediated cycle, the hydrolysis of ATP by rubisco-activase elicits a conformational change of rubisco that reduces its binding affinity for sugar phosphates in presence of light
Rubisco activase in some species is activated by light through a redox mechanism
These light actuated ion fluxes decreases pH and increases that of Mg2+ by 2 to 5 mM, activate enzymes of the Calvin–Benson cycle that require Mg2+ for catalysis
