Question

Explain why photosynthesis generally produces a large amount of Rubisco. Explain from the perspective of an FBI why C4 plants keep rubisco in bundle sheath cells.

Answer 1

Rubisco catalyse the is an enzyme, it full carbon fixation in calvin cycle. Rubisco form is ribulose - 1,5-bisphosphate carboxylase. * Rubisco converts the carbon dios the carbon which is ultimately converted by the photo synthetic organisms and as a energy rich molecules ie glucose Rubisco photosynthetic organism Atmospheric CO₂ , carbon fixation Energy molecules (sugars) * Rubisco rate limiting step in photosythetic carbon fixation incorporates co2 into plants

* Cu plants use phosphoenol pyruvate ! Phocnol pyruvate (PEP) in carbon fixation instead of rubisco. * Phosphoenolpyruvate has no oxygenase e has no oxygenase activity more affinity for coz than rubisco. and it has * Rabisco does the carboxylation in budle sheath. * In in bundle-sheath C4 plants Rubisco fixation of oxygen to overcome the waste rather than co2. nism cyphants attracts com Phosphoenol pyruvate hon decarboxylation occur in bandle sheath by rubisco energy molecules.
