How does rubisco “decide” whether to act as an oxygenase or a carboxylase?
a. Rubisco has 10 times more affinity for O2 than CO2; therefore, it favors O2 fixation.
b. If O2 is relatively abundant, rubisco acts as a carboxylase.
c. If O2 predominates, rubisco fixes it and the Calvin–Benson cycle occurs.
d. Photorespiration is more likely at low temperatures.
e. As the ratio of CO2 to O2 falls in the leaf, the reaction of rubisco with O2 is favored, and photorespiration proceeds.
