Question

When CO2: O2 is approximately 1, RuBisCO has a lower affinity for CO2. True or false?

(a) True

(b) False

The question was posed to me in an international level competition.

I need to ask this question from Higher Plants Photosynthesis topic in section Photosynthesis in Higher Plants of Biology – Class 11

Answer 1

Correct answer is (b) False

The best I can explain: RuBisCO or Ribulose-1,5-bisphosphate carboxylase oxygenase catalyses the formation of 3PGA from RuBP and carbon dioxide during Calvin cycle. RuBP is the primary carbon dioxide acceptor molecule.
