Question

RuBisCo occurs in high quantity as it is

• A. An oxygenase
• B. Catalysing reversible reaction
• C. Degraded rapidly
• D. Very slow acting enzyme

Answer 1

The correct option is D Very slow acting enzyme

A) RuBisCO is both an oxygenase and a carboxylase. It has more affinity for carbon dioxide. Its quantity does not affect this property.

B) RuBisCO does not catalyse any reversible reactions.

C) RuBisCO is stable and does not get degraded easily.
D) RuBisCO is a very slow acting enzyme and hence, is required in large amounts.
So the correct answer is 'Very slow acting enzyme'.
