In hot and dry conditions, the concentration of CO2 in leaves drops. Which catalytic activity does the enzyme RuBisCO exhibit under these specific circumstances?
Q1. In hot and dry conditions, the concentration of CO2 in leaves drops. Which catalytic activity does the enzyme RuBisCO exhibit under these specific circumstances?
Answer: Oxygenase
Explanation: RuBisCO acts as an oxygenase when CO2 levels are low and O2 is high; carboxylase activity is its standard role in photosynthesis.
