Notes from NEET topper
Carboxylase-oxygenase activity of Rubisco:
Rubisco is characterised by the fact that its active site can bind to both CO2 and O2. RuBisCO has a much greater affinity for CO2 when the CO2: O2 is nearly equal. It is the relative concentration of O2 and CO2 that determines which of the two will bind to the enzyme. The oxygenase activity occurs at:
a. High O2 and low CO2 conditions
b. High temperatures.
c. High light intensity
d. Low Co2/O2 ratio
