In C4 plant RuBisCO activate during:-
Open in App
Solution
The correct option is A Day
RuBisCOcatalyzes the key reaction in which RUBP acts as an acceptor for CO2 forming two molecules of PGA. The competing reaction with O2 leads to the formation of phosphoglycolate, which is recycled through photorespiration. Thus, the activity of Rubisco is majorly depended on light activation and dark inactivation. The light reactions of photosynthesis produce ATP and activation of RuBisCO is ATP-dependent, which furnishes a mechanism regarding the light-dependent activation of the enzyme. However, activation of RuBisco activase and transformation of RuBisCO in its inactive form need transport of electron and that can only occur in presence of light or during the day. So, the correct answer is option A.
