Question

Rubisco has a dual role.comment

Answer 1

RuBP Carboxylase-Oxygenase (Ribulose- 1, 5-bisphosphate Carboxylase-Oxygenase) is also called RUBISCO. It has dual function as it has both carboxylasse and oxygenase activity. It is the most abundant enzyme complex found on the earth. It can act on the two substrates: Carbon dioxide (carboxylase activity- for carbon dioxide assimilation into glucose during photosynthesis) and Oxygen (oxygenase activity-causing photorespiration, decreasing the photosynthetic efficiency of plants).
