Question

Which are the $C{O}_2$ fixing enzymes of rice and where are they located?

• A. RUBISCO in bundle sheath cells and PEP carboxylase in mesophyll cells.
• B. RUBISCO in mesophyll cells and PEP carboxylase in bundle sheath cells.
• C. RUBISCO and PEP carboxylase in bundle sheath cells.
• D. RUBISCO in mesophyll cells.

Answer 1

The correct option is D

RUBISCO in mesophyll cells.

Rice is a $C_3$ plant and it contains only RUBISCO as the $C{O}_2$ fixing enzyme, located in the matrix of its chloroplasts of the mesophyll cells.
