Which of the following statements is incorrect?
In C4 plants, the site of RuBisCo activity is in mesophyll cell
The substrate molecule for RuBisCo activity is a 5-carbon compound
RuBisCo action requires ATP and NADPH
RuBisCo is a bifunctional enzymes
C4 plants have specialized leaf anatomy with two different types of photosynthetic cells: mesophyll cells (on the exterior of the leaf, near stomata) and bundle sheath cells (in the interior of the leaf, far away from stomata). Rubisco is located in bundle sheath cells, but not in mesophyll cells.
