Question

RuBisCO is

• A. RuBisCO carboxylase
• B. RuBisCO oxygenase
• C. RuBisCO carboxylase-oxygenase
• D. RuBisCO carboxy dismutase

Answer 1

Answer: (C)

RuBisCO carboxylase-oxygenase

The enzyme RuBisCO carries out photosynthetic carboxylation of RuBP The enzyme was previously called as carboxydismutase. RuBisCO is the most abundant protein of the biological world. RuBisCO is located int the stroma on the outer surface of thylakoid membranes. As it is capable of carrying out both carboxylation and oxygenation and oxygenation reaction in C3C3 and C4C4 plants respectively, thus it is correctly named as RuBP carboxylase-oxygenase.

So, the correct answer is 'RuBisCO carboxylase-oxygenase'.
