Question

Select the incorrect statement about RuBisCO.

• A. It is the most abundant enzyme
• B. It has much greater affinity for CO${}_2$ than for O${}_2$
• C. In C${}_3$ plants some O${}_2$ does bind to RuBisCO
• D. RuBP combines with O${}_2$ to form 3 molecules of 3-PGA, this reaction is also catalysed by RuBisCO

Answer 1

The correct option is D RuBP combines with O${}_2$ to form 3 molecules of 3-PGA, this reaction is also catalysed by RuBisCO

RuBP combines with O${}_2$ to form one molecule of PGA and one molecule of phosphoglycolate and this reaction is catalysed by RuBisCO.
