Question
What conditions enable RuBisCO to function as an oxygenase? Explain the ensuring process.
✓
Answer
Carboxylation is the most crucial step of the Calvin cycle, where CO2 is utilised for the carboxylation of RuBP. This reaction is catalysed by the enzyme RuBP carboxylase, which results in the formation of two molecules of 3-PGA. Since, this enzyme also has an oxygenation activity, it would be more correct to call it RuBP carboxylase oxygenase or RuBisCO.
