Name the enzyme that catalyses carboxylation as well as oxygenation reaction. In which cell organelle is this enzyme found and in what way is that organelle different in the mesophyll and bundle sheath cells ?


#2

Rubisco enzyme : It catalyses carboxylation and oxygenation reactions. It is found in the chloroplast (cell organelle).
Chloroplasts in mesophyll cells are granal but chloroplast of bundle sheath cells are arganal. Granal chloroplasts have thylakoids stalked to form grana (as in C3 plants). Agranal chloroplasts are without grana but the thylakoids are found only as stroma lamellae
